Justice Scalia, delivered the opinion of the Court.
The principal question presented by this case is whether a guerrilla organization's attempt to coerce a person into performing military service necessarily constitutes "persecution on account of . . . political opinion" under § 101(a)(42) of the Immigration and Nationality Act, as added, 94 Stat. 102, 8 U. S. C. § 1101(a)(42).

I
Respondent Elias-Zacarias, a native of Guatemala, was apprehended in July 1987 for entering the United States without inspection. In deportation proceedings brought by petitioner Immigration and Naturalization Service (INS), Elias-Zacarias conceded his deportability but requested asylum and withholding of deportation.
The Immigration Judge summarized Elias-Zacarias' testimony as follows:
"[A]round the end of January in 1987 [when EliasZacarias was 18], two armed, uniformed guerrillas with handkerchiefs covering part of their faces came to his home. Only he and his parents were there. . . . [T]he guerrillas asked his parents and himself to join with them, but they all refused. The guerrillas asked them why and told them that they would be back, and that they should think it over about joining them.

*480 "[Elias-Zacarias] did not want to join the guerrillas because the guerrillas are against the government and he was afraid that the government would retaliate against him and his family if he did join the guerrillas. [H]e left Guatemala at the end of March [1987] .. . because he was afraid that the guerrillas would return." App. to Pet. for Cert. 40a41a.
The Immigration Judge understood from this testimony that Elias-Zacarias' request for asylum and for withholding of deportation was "based on this one attempted recruitment by the guerrillas." Id., at 41a. She concluded that EliasZacarias had failed to demonstrate persecution or a wellfounded fear of persecution on account of race, religion, nationality, membership in a particular social group, or political opinion, and was not eligible for asylum. See 8 U. S. C. §§ 1101(a)(42), 1158(a). She further concluded that he did not qualify for withholding of deportation.
The Board of Immigration Appeals (BIA) summarily dismissed Elias-Zacarias' appeal on procedural grounds. EliasZacarias then moved the BIA to reopen his deportation hearing so that he could submit new evidence that, following his departure from Guatemala, the guerrillas had twice returned to his family's home in continued efforts to recruit him. The BIA denied reopening on the ground that even with this new evidence Elias-Zacarias had failed to make a prima facie showing of eligibility for asylum and had failed to show that the results of his deportation hearing would be changed.
The Court of Appeals for the Ninth Circuit, treating the BIA's denial of the motion to reopen as an affirmance on the merits of the Immigration Judge's ruling, reversed. 921 F. 2d 844 (1990). The court ruled that acts of conscription by a nongovernmental group constitute persecution on account of political opinion, and determined that Elias-Zacarias had a "well-founded fear" of such conscription. Id., at 850 852. We granted certiorari. 500 U. S. 915 (1991).


*481 II
Section 208(a) of the Immigration and Nationality Act, 8 U. S. C. § 1158(a), authorizes the Attorney General, in his discretion, to grant asylum to an alien who is a "refugee" as defined in the Act, i. e., an alien who is unable or unwilling to return to his home country "because of persecution or a well-founded fear of persecution on account of race, religion, nationality, membership in a particular social group, or political opinion." § 101(a)(42)(A), 8 U. S. C. § 1101(a)(42)(A). See INS v. Cardoza-Fonseca, 480 U. S. 421, 423, 428, n. 5 (1987). The BIA's determination that Elias-Zacarias was not eligible for asylum must be upheld if "supported by reasonable, substantial, and probative evidence on the record considered as a whole." 8 U. S. C. § 1105a(a)(4). It can be reversed only if the evidence presented by Elias-Zacarias was such that a reasonable factfinder would have to conclude that the requisite fear of persecution existed. NLRB v. Columbian Enameling & Stamping Co., 306 U. S. 292, 300 (1939).[1]
The Court of Appeals found reversal warranted. In its view, a guerrilla organization's attempt to conscript a person into its military forces necessarily constitutes "persecution on account of . . . political opinion," because "the person resisting forced recruitment is expressing a political opinion hostile to the persecutor and because the persecutors' motive in carrying out the kidnapping is political." 921 F. 2d, at 850. The first half of this seems to us untrue, and the second half irrelevant.
*482 Even a person who supports a guerrilla movement might resist recruitment for a variety of reasonsfear of combat, a desire to remain with one's family and friends, a desire to earn a better living in civilian life, to mention only a few. The record in the present case not only failed to show a political motive on Elias-Zacarias' part; it showed the opposite. He testified that he refused to join the guerrillas because he was afraid that the government would retaliate against him and his family if he did so. Nor is there any indication (assuming, arguendo, it would suffice) that the guerrillas erroneously believed that Elias-Zacarias' refusal was politically based.
As for the Court of Appeals' conclusion that the guerrillas' "motive in carrying out the kidnapping is political": It apparently meant by this that the guerrillas seek to fill their ranks in order to carry on their war against the government and pursue their political goals. See 921 F. 2d, at 850 (citing Arteaga v. INS, 836 F. 2d 1227, 1232, n. 8 (CA9 1988)); 921 F. 2d, at 852. But that does not render the forced recruitment "persecution on account of . . . political opinion." In construing statutes, "we must, of course, start with the assumption that the legislative purpose is expressed by the ordinary meaning of the words used." Richards v. United States, 369 U. S. 1, 9 (1962); see Cardoza-Fonseca, supra, at 431; INS v. Phinpathya, 464 U. S. 183, 189 (1984). The ordinary meaning of the phrase "persecution on account of . . . political opinion" in § 101(a)(42) is persecution on account of the victim's political opinion, not the persecutor's. If a Nazi regime persecutes Jews, it is not, within the ordinary meaning of language, engaging in persecution on account of political opinion; and if a fundamentalist Moslem regime persecutes democrats, it is not engaging in persecution on account of religion. Thus, the mere existence of a generalized "political" motive underlying the guerrillas' forced recruitment is inadequate to establish (and, indeed, goes far to refute) the proposition that Elias-Zacarias fears persecution on account of political opinion, as § 101(a)(42) requires.
*483 Elias-Zacarias appears to argue that not taking sides with any political faction is itself the affirmative expression of a political opinion. That seems to us not ordinarily so, since we do not agree with the dissent that only a "narrow, grudging construction of the concept of `political opinion,' " post, at 487, would distinguish it from such quite different concepts as indifference, indecisiveness, and risk averseness. But we need not decide whether the evidence compels the conclusion that Elias-Zacarias held a political opinion. Even if it does, Elias-Zacarias still has to establish that the record also compels the conclusion that he has a "well-founded fear" that the guerrillas will persecute him because of that political opinion, rather than because of his refusal to fight with them. He has not done so with the degree of clarity necessary to permit reversal of a BIA finding to the contrary; indeed, he has not done so at all.[2]
Elias-Zacarias objects that he cannot be expected to provide direct proof of his persecutors' motives. We do not require that. But since the statute makes motive critical, he must provide some evidence of it, direct or circumstantial. And if he seeks to obtain judicial reversal of the BIA's determination, he must show that the evidence he presented was *484 so compelling that no reasonable factfinder could fail to find the requisite fear of persecution. That he has not done.
The BIA's determination should therefore have been upheld in all respects, and we reverse the Court of Appeals' judgment to the contrary.
It is so ordered. 
Justice Stevens, with whom Justice Blackmun and Justice O'Connor join, dissenting.
Respondent refused to join a guerrilla organization that engaged in forced recruitment in Guatemala. He fled the country because he was afraid the guerrillas would return and "take me and kill me."[1] After his departure, armed guerrillas visited his family on two occasions searching for him. In testimony that the hearing officer credited, he stated that he is still afraid to return to Guatemala because "these people" can come back to "take me or kill me."[2]
It is undisputed that respondent has a well-founded fear that he will be harmed, if not killed, if he returns to Guatemala. It is also undisputed that the cause of that harm, if it should occur, is the guerrilla organization's displeasure with his refusal to join them in their armed insurrection against the government. The question of law that the case presents is whether respondent's well-founded fear is a "fear of persecution on account of . . . political opinion" within the meaning of § 101(a)(42) of the Immigration and Nationality Act.[3]
*485 If respondent were to prevail, as he did in the Court of Appeals, 921 F. 2d 844 (CA9 1990), he would be classified as a "refugee" and therefore be eligible for a grant of asylum. He would not be automatically entitled to that relief, however, because "the Attorney General is not required to grant asylum to everyone who meets the definition of refugee." INS v. Cardoza-Fonseca, 480 U. S. 421, 428, n. 5 (1987) (emphasis in original). Instead, § 208 of the Act provides that the Attorney General may, "in [his] discretion," grant asylum to refugees.[4]
*486 Today the Court holds that respondent's fear of persecution is not "on account of . . . political opinion" for two reasons. First, he failed to prove that his refusal to join the guerrillas was politically motivated; indeed, he testified that he was at least in part motivated by a fear that government forces would retaliate against him or his family if he joined the guerrillas. See ante, at 482-483. Second, he failed to prove that his persecutors' motives were political. In particular, the Court holds that the persecutors' implicit threat to retaliate against respondent "because of his refusal to fight with them," ante, at 483, is not persecution on account of political opinion. I disagree with both parts of the Court's reasoning.

I
A political opinion can be expressed negatively as well as affirmatively. A refusal to support a causeby staying home on election day, by refusing to take an oath of allegiance, or by refusing to step forward at an induction centercan express a political opinion as effectively as an affirmative statement or affirmative conduct. Even if the refusal is motivated by nothing more than a simple desire to continue living an ordinary life with one's family, it is the kind of political expression that the asylum provisions of the statute were intended to protect.
As the Court of Appeals explained in Bolanos-Hernandez  v. INS, 767 F. 2d 1277 (CA9 1985):
"Choosing to remain neutral is no less a political decision than is choosing to affiliate with a particular political faction. Just as a nation's decision to remain neutral is a political one, see, e. g., Neutrality Act of 1939, 22 U. S. C. §§ 441-465 (1982), so is an individual's. When a person is aware of contending political forces and affirmatively *487 chooses not to join any faction, that choice is  a political one. A rule that one must identify with one of two dominant warring political factions in order to possess a political opinion, when many persons may, in fact, be opposed to the views and policies of both, would frustrate one of the basic objectives of the Refugee Act of 1980to provide protection to all victims of persecution regardless of ideology. Moreover, construing `political opinion' in so short-sighted and grudging a manner could result in limiting the benefits under the ameliorative provisions of our immigration laws to those who join one political extreme or another; moderates who choose to sit out a battle would not qualify." Id.,  at 1286 (emphasis in original; footnote omitted).
The narrow, grudging construction of the concept of "political opinion" that the Court adopts today is inconsistent with the basic approach to this statute that the Court endorsed in INS v. Cardoza-Fonseca, supra. In that case, relying heavily on the fact that an alien's status as a "refugee" merely makes him eligible for a discretionary grant of asylumas contrasted with the entitlement to a withholding of deportation authorized by § 243(h) of the Actthe Court held that the alien's burden of proving a well-founded fear of persecution did not require proof that persecution was more likely than not to occur. We explained:
"Our analysis of the plain language of the Act, its symmetry with the United Nations Protocol, and its legislative history, lead inexorably to the conclusion that to show a `well-founded fear of persecution,' an alien need not prove that it is more likely than not that he or she will be persecuted in his or her home country. We find these ordinary canons of statutory construction compelling, even without regard to the longstanding principle of construing any lingering ambiguities in deportation statutes in favor of the alien. See INS v. Errico, 385

*488 U. S. 214, 225 (1966); Costello v. INS, 376 U. S. 120, 128 (1964); Fong Haw Tan v. Phelan, 333 U. S. 6, 10 (1948).
"Deportation is always a harsh measure; it is all the more replete with danger when the alien makes a claim that he or she will be subject to death or persecution if forced to return to his or her home country. In enacting the Refugee Act of 1980 Congress sought to `give the United States sufficient flexibility to respond to situations involving political or religious dissidents and detainees throughout the world.' H. R. Rep. [96-608, p. 9 (1979)]. Our holding today increases that flexibility by rejecting the Government's contention that the Attorney General may not even consider granting asylum to one who fails to satisfy the strict § 243(h) standard. Whether or not a `refugee' is eventually granted asylum is a matter which Congress has left for the Attorney General to decide. But it is clear that Congress did not intend to restrict eligibility for that relief to those who could prove that it is more likely than not that they will be persecuted if deported." 480 U. S., at 449-450.
Similar reasoning should resolve any doubts concerning the political character of an alien's refusal to take arms against a legitimate government in favor of the alien. In my opinion, the record in this case is more than adequate to support the conclusion that this respondent's refusal was a form of expressive conduct that constituted the statement of a "political opinion" within the meaning of § 208(a).[5]


*489 II
It follows as night follows day that the guerrillas' implied threat to "take" him or to "kill" him if he did not change his position constituted threatened persecution "on account of" that political opinion. As the Court of Appeals explained in Bolanos-Hernandez: 
"It does not matter to the persecutors what the individual's motivation is. The guerrillas in El Salvador do not inquire into the reasoning process of those who insist on remaining neutral and refuse to join their cause. They are concerned only with an act that constitutes an overt manifestation of a political opinion. Persecution because of that overt manifestation is persecution because of a political opinion." 767 F. 2d, at 1287.[6]
It is important to emphasize that the statute does not require that an applicant for asylum prove exactly why his persecutors would act against him; it only requires him to show that he has a "well-founded fear of persecution on account of. . . political opinion." As we recognized in INS v. CardozaFonseca, the applicant meets this burden if he shows that there is a "`reasonable possibility' " that he will be persecuted *490 on account of his political opinion. 480 U. S., at 440 (quoting INS v. Stevic, 467 U. S. 407, 425 (1984)). Because respondent expressed a political opinion by refusing to join the guerrillas, and they responded by threatening to "take" or to "kill" him if he did not change his mind, his fear that the guerrillas will persecute him on account of his political opinion is well founded.[7]
Accordingly, I would affirm the judgment of the Court of Appeals.
NOTES
[*]   Briefs of amici curiae urging affirmance were filed for the American Immigration Lawyers Association by Kevin R. Johnson, Joshua R. Floum, and Robert Rubin; for the Lawyers Committee for Human Rights et al. by Arthur C. Helton, O. Thomas Johnson, Jr., and Andrew I. Schoenholtz; and for the United Nations High Commissioner for Refugees by Arthur L. Bentley III and Julian Fleet. 
[1]  Quitebeside the point, therefore, is the dissent's assertion that "the record in this case is more than adequate to support the conclusion that this respondent's refusal [to join the guerrillas] was a form of expressive conduct that constituted the statement of a `political opinion,' "post, at 488 (emphasis added). To reverse the BIA finding we must find that the evidence not only supports that conclusion, but compels itand also compels the further conclusion that Elias-Zacarias had a well-founded fear that the guerrillas would persecute him because of that political opinion.
[2]  The dissent misdescribes the record on this point in several respects. For example, it exaggerates the "well foundedness" of whatever fear Elias-Zacarias possesses, by progressively transforming his testimony that he was afraid the guerrillas would "`take me or kill me,'" post, at 484, into, first, "the guerrillas' implied threat to `take' him or to `kill' him," post, at 489 (emphasis added), and, then, into the flat assertion that the guerrillas "responded by threatening to `take' or to `kill' him," post, at 490 (emphasis added). The dissent also erroneously describes it as "undisputed" that the cause of the harm Elias-Zacarias fears, if that harm should occur, will be "the guerrilla organization's displeasure with his refusal to join them in their armed insurrection against the government." Post, at 484 (emphasis added). The record shows no such concession by the INS, and all Elias-Zacarias said on the point was that he feared being taken or killed by the guerrillas. It is quite plausible, indeed likely, that the taking would be engaged in by the guerrillas in order to augment their troops rather than show their displeasure; and the killing he feared might well be a killing in the course of resisting being taken.

[3]  Section 101(a)(42), as codified in 8 U. S. C. § 1101(a)(42), provides:

"(a) As used in this chapter
. . . . .
"(42) The term `refugee' means (A) any person who is outside any country of such person's nationality or, in the case of a person having no nationality, is outside any country in which such person last habitually resided, and who is unable or unwilling to return to, and is unable or unwilling to avail himself or herself of the protection of, that country because of persecution or a well-founded fear of persecution on account of race, religion, nationality, membership in a particular social group, or political opinion, or (B) in such special circumstances as the President after appropriate consultation (as defined in section 1157(e) of this title) may specify, any person who is within the country of such person's nationality or, in the case of a person having no nationality, within the country in which such person is habitually residing, and who is persecuted or who has a wellfounded fear of persecution on account of race, religion, nationality, membership in a particular social group, or political opinion. The term `refugee' does not include any person who ordered, incited, assisted, or otherwise participated in the persecution of any person on account of race, religion, nationality, membership in a particular social group, or political opinion."
[4]  Section 208(a) of the Act, as codified at 8 U. S. C. § 1158(a), provides:

"The Attorney General shall establish a procedure for an alien physically present in the United States or at a land border or port of entry, irrespective of such alien's status, to apply for asylum, and the alien may be granted asylum in the discretion of the Attorney General if the Attorney General determines that such alien is a refugee within the meaning of section 1101(a)(42)(A) of this title."
As we recognized in INS v. Cardoza-Fonseca, 480 U. S. 421, 444-445 (1987):
"`The [House] Committee carefully considered arguments that the new definition might expand the numbers of refugees eligible to come to the United States and force substantially greater refugee admissions than the country could absorb. However, merely because an individual or group comes within the definition will not guarantee resettlement in the United States.' H. R. Rep. [96-608, p. 10 (1979)].
". . . Congress has assigned to the Attorney General and his delegates the task of making these hard individualized decisions; although Congress could have crafted a narrower definition, it chose to authorize the Attorney General to determine which, if any, eligible refugees should be denied asylum."
[5]  Here, respondent not only engaged in expressive conduct by refusing to join the guerrilla organization but also explained that he did so "[b]ecause they see very well, that if you join the guerrillas . .. then you are against the government. You are against the government and if you join them then it is to die there. And, then the government is against you and against your family." App. to Brief in Opposition 5a. Respondent thus expressed the political view that he was for the government and against the guerrillas. The statute speaks simply in terms of a political opinion and does not require that the view be well developed or elegantly expressed.
[6]  The Government has argued that respondent's statement is analogous to that of a person who leaves a country to avoid being drafted into military service. The INS has long recognized, however, that the normal enforcement of Selective Service laws is not "persecution" within the meaning of the statute even if the draftee's motive is political. Thus, while holding that an Afghan soldier who refused to fight under Soviet command qualified as a political refugee, Matter of Salim, 18 I. & N. Dec. 311 (BIA 1982), the INS has adhered "to the long-accepted position that it is not persecution for a country to require military service of its citizens." Matter of AG, 19 I. & N. Dec. 502, 506 (BIA 1987); cf. United Nations High Commissioner for Refugees, Handbook on Procedures and Criteria for Determining Refugee Status ¶ 167 (1979) ("Fear of prosecution and punishment for desertion or draft-evasion does not in itself constitute wellfounded fear of persecution under the [1967 United Nations Protocol Relating to the Status of Refugees]").
[7]  In response to this dissent, the Court suggests that respondent and I have exaggerated the "well foundedness" of his fear. See ante, at 483, n. 2. The Court's legal analysis, however, would produce precisely the same result no matter how unambiguous the guerrillas' threatened retaliation might have been. Moreover, any doubts concerning the sinister character of a suggestion to "think it over" delivered by two uniformed masked men carrying machine guns should be resolved in respondent's favor.
