   Before KANNE, SCUDDER, and ST. EVE, Circuit Judges.
    PER CURIAM. Federal agents thwarted Abdella Tounisi’s
plans to travel to Syria to join Jabhat al-Nusrah, a militant ter-
rorist group associated with al-Qaida, when they arrested
him at an airport gate while awaiting a flight to Turkey. He
pleaded guilty to knowingly attempting to provide material
support to a foreign terrorist organization, and the district
court sentenced him to the statutory maximum of 15 years in
prison and a lifetime of supervised release. Tounisi argues on
2                                                  No. 17-3325

appeal that the district judge procedurally erred at sentencing
in four ways: (1) he did not sufficiently address Tounisi’s mit-
igating arguments; (2) he did not adequately explain the
length of imprisonment; (3) he failed to properly consider the
18 U.S.C. § 3553(a) factors; and (4) he did not adequately ex-
plain the length of supervised release. Because the judge did
not make any of these errors, we affirm the judgment.
                        I. Background
    By early 2013, Tounisi had decided to join
Jabhat al-Nusrah in Syria. He had watched videos of and read
articles about its violent operations and its links to al-Qaida.
His parents learned of his plans and attempted to stop him by
taking away his passport in January. Undeterred, Tounisi ap-
plied for an expedited passport, reporting that his previous
one had been lost and that he intended to travel to Jordan. He
also opened a post-office mailbox just to receive the new pass-
port. Later that month he visited a purported recruitment
website for Jabhat al-Nusrah and emailed the listed contact
person, who was actually an FBI agent, about his strategy to
travel to Syria by flying to Istanbul, Turkey, then bussing to
Gaziantep, a Turkish city bordering Syria. He explained that
he would seize the opportunity to attain martyrdom if it pre-
sented itself.
    Tounisi, then 18 years old, solidified his plans in April
2013. He bought a ticket for a flight on April 19 to Istanbul.
The day before his flight, the “recruiter” sent him a bus ticket
for Istanbul to Gaziantep and promised that “brothers”
would be waiting to take him to a training camp in Syria.
Tounisi responded by describing what he would be wearing
when he arrived. As scheduled, he went to O’Hare Interna-
tional Airport to catch his flight to Turkey. He made it as far
No. 17-3325                                                   3

as the airport gate before federal agents approached, ques-
tioned, and ultimately arrested him. Tounisi was charged
with knowingly attempting to provide material support to a
foreign terrorist organization, see 18 U.S.C. § 2339B(a)(1), and
making false statements in connection with an offense involv-
ing international terrorism, see id. § 1001(a)(2). He pleaded
guilty to the first charge in exchange for dismissal of the sec-
ond.
    A probation officer determined that Tounisi had a total of-
fense level of 37 and a criminal history category of VI, each
heavily influenced by the offense qualifying as a federal ter-
rorism crime: the offense level was increased by 12 and the
criminal history category automatically raised from I to VI.
See U.S.S.G. § 3A1.4. The guideline imprisonment range
would have been 360 months to life with those extended pa-
rameters. But that range exceeded the then-statutory maxi-
mum of 180 months, which thus became the applicable advi-
sory guideline imprisonment term. Because Tounisi’s terror-
ism crime also posed a foreseeable risk of injury to another
person, the policy statements for supervised release recom-
mended a term of 1 year to life. See U.S.S.G. § 5D1.2(b)(1).
    In his sentencing memorandum, Tounisi advocated for an
84-month prison sentence followed by a 10-year term of su-
pervised release. He relied on a report by Dr. Marc Sageman,
an expert in “forensic psychiatry and terrorism,” who had in-
terviewed him. Dr. Sageman concluded that Tounisi was “at
no greater risk than the normal population of being a danger
to the public,” and that he was “not so brainwashed ideolog-
ically” that he remained a risk to run off to fight. Tounisi
agreed that the guidelines were correctly calculated but ar-
gued that the increases for a terrorism offense resulted in an
4                                                  No. 17-3325

overstated sentencing range because (1) he was placed in the
highest criminal history category despite having no prior
criminal history; and (2) he did not target the United States
but instead, in a misguided effort, meant to help combat the
dictatorial Syrian government.
    Tounisi also highlighted several of the 18 U.S.C. § 3553(a)
factors. First, as to his history and characteristics,
id. § 3553(a)(1), he had struggled with depression and isola-
tion resulting from his family’s financial struggles and the re-
ligious and racial discrimination they experienced, so he had
turned to religion to cope. Now that his plans had been
thwarted, he was remorseful and thankful he had not suc-
ceeded. When looking at the nature and circumstances of the
offense, id., Tounisi reiterated that his choice to join Jabhat
al-Nusrah was influenced by his isolation and motivated by
his desire to help fight the Syrian government rather than a
wish to join a terrorist group. He explained that he was
friends with Adel Daoud, an 18-year-old from his mosque
who tried to detonate a bomb in downtown Chicago. Tounisi
had briefly considered helping Daoud but later tried, to no
avail, to dissuade him from attempting to carry out the attack.
    Additionally, Tounisi argued against a significant need for
deterrence, id. § 3553(a)(2)(B), and for further punishment, id.
§ 3553(a)(2)(A). He asserted that specific deterrence was un-
necessary, citing empirical studies showing that (1) being a
first-time offender, (2) having strong family ties, and (3) en-
during swift and sure punishment all greatly decreased his
chances of reoffending. Moreover, his youth and immaturity
partially explained his conduct, and he would have matured
by his release from prison after his requested 84-month sen-
tence. As for general deterrence, Tounisi pointed to studies
No. 17-3325                                                   5

showing that other consequences related to prosecution (so-
cial stigma, etc.) were more effective deterrents than incarcer-
ation. Further, Tounisi already had been incarcerated for al-
most 20 percent of his life and had to carry the stigma of being
a “terrorist” and felon forever, so punishment beyond his sug-
gested sentence would not be “just.”
    Separately, Tounisi suggested changes to a few proposed
conditions of supervised release but otherwise did not object
to them. He requested a 10-year term, or alternatively, the
possibility of early termination of a longer term.
    The government argued for a 15-year term of imprison-
ment. It submitted that the offense was particularly serious
despite Tounisi’s stated goal of fighting the oppressive Syrian
government. After all, by joining a terrorist group associated
with al-Qaida, he was joining an enemy of the United States,
and his plans easily could have backfired: he could have
killed innocent Syrian people or been forced to return to the
United States to commit an attack here. The government also
pointed to Tounisi’s perseverance in committing his offense.
He had not been deterred by FBI questioning after Daoud’s
arrest, his family trying to stop him by taking away his pass-
port, or his pursuit of educational opportunities.
    At the sentencing hearing, Tounisi repeated the mitigating
arguments: his difficult background, his remorse, his ill-ad-
vised friendship with Daoud, and his youth. Tounisi again
emphasized that his offense was less severe than a typical ter-
rorism offense, and that the goals of general deterrence and
just punishment could be satisfied without a 15-year sentence.
Counsel did not mention the proposed 10-year term of super-
vised release. The government described Tounisi as someone
who “was not going to be deterred,” reiterating the lengths he
6                                                  No. 17-3325

undertook in attempting to get to Syria. The government also
argued that general deterrence was paramount in order to
dissuade others who might be young and naïve from follow-
ing in Tounisi’s footsteps.
    After the parties’ arguments, the district judge solicited
their views on the proposed conditions of supervised release
(not the term’s length). He then repeated the parties’ written
and oral sentencing arguments before discussing his view of
the § 3553(a) factors. The judge noted that Tounisi had been
struggling in life but concluded that those difficulties “cannot
excuse the seriousness of his crime,” which weighed “heav-
ily.” He remarked that many immigrants face discrimination,
but most do not resolve to join an international terrorist or-
ganization. The judge opined that, despite Tounisi’s sup-
posed noble intentions, he still was aligning himself with a
group that advocates for the destruction of the United States
and had placed himself at risk of becoming “a pawn” in a fu-
ture attack against the country. The judge thus thought his
crime, though never consummated, ranked “at the top.”
    The judge also concluded that Tounisi’s actions showed
that he needed to learn respect for the law. He had not warned
anyone about Daoud’s plans, had not been deterred even af-
ter speaking with the FBI about his friend’s arrest, and had
lied to agents when they caught him at the airport. Next, the
judge said that “there is a definite need to deter the defendant
and others” from committing terrorism offenses. He empha-
sized that he had considered Tounisi’s argument that specific
deterrence was unnecessary but said that “a great need for
general deterrence” existed because people must know that
they will be punished for “assisting terrorist organizations.”
No. 17-3325                                                    7

The judge, moreover, thought that the public needed protec-
tion from Tounisi because—irrespective of his motivations
and newfound remorse—he had been willing to hurt inno-
cents. The judge also briefly reviewed Dr. Sageman’s conclu-
sions about Tounisi being at a decreased risk of recidivism.
    Addressing Tounisi directly, the judge noted that he had
deliberately thrown away his opportunity to attend college
and help people in a positive way in order to “join a bunch of
thugs that take pride in cowardly killings,” even defying his
family to do so. The judge sentenced him to 180 months in
prison—the statutory maximum—adding that the factors
“would warrant a significantly higher sentence” if there had
not been a cap. Having “considered the factors in Section
3553(a) in determining the conditions of supervised release,”
the judge imposed a lifetime term and repeated those condi-
tions.
                        II. Discussion
    On appeal, Tounisi asserts that the district judge erred
only procedurally in determining his sentence, but he chal-
lenges nearly every aspect of the judge’s reasoning. Tounisi,
in short, wants de novo review of all the issues he raises, even
if they touch on the substantive reasonableness of the sen-
tence. See United States v. Thompson, 864 F.3d 837, 841 (7th Cir.
2017), cert. denied, 138 S. Ct. 704 (2018) (explaining procedural
challenges to sentence are reviewed de novo and substantive
challenges are reviewed for abuse of discretion).
   First, Tounisi takes issue with how the judge handled his
mitigating arguments, contending that he repeated them but
did not explain how he evaluated them. A district judge must
8                                                    No. 17-3325

address the defendant’s principal arguments made in mitiga-
tion, but the explanation can be implicit or imprecise and does
not need to be extensive. See United States v. Reed, 859 F.3d
468, 472–73 (7th Cir. 2017); United States v. Davis, 764 F.3d 690,
694 (7th Cir. 2014). It must be detailed enough that we can
recognize that the judge “considered the argument and ha[d]
a reasoned basis” for how he weighed it. Davis, 764 F.3d
at 694. The judge did that here.
    He acknowledged several mitigating factors—Tounisi’s
lack of criminal history, mistreatment by others, youth, and
depression and isolation—but Tounisi says he then “baldly
assert[ed]” that they could not “excuse” the severity of the
crime. The judge understandably considered these points to-
gether, however, because the first sentencing factor encom-
passes both “the nature and circumstances of the offense” and
“the history and characteristics of the defendant.” 18 U.S.C.
§ 3553(a)(1). And as he explained more than once, the judge
thought that the offense was still gravely serious in spite of
Tounisi’s argument that his was not a typical “terrorism” of-
fense and other mitigating arguments. In context, “excuse”
meant “outweigh”: the nature and severity of the offense
overshadowed the mitigating factors.
    Tounisi also contends that the judge mishandled his miti-
gating argument about specific deterrence. He says that the
judge’s remarks lacked logic and ignored the parties’ posi-
tions. But the judge largely accepted that, as the parties
agreed, specific deterrence was unnecessary. Though he re-
marked on the “definite need” to deter Tounisi (and “oth-
ers”), he then repeated Tounisi’s primary arguments about
why specific deterrence was unimportant. Relatedly, Tounisi
No. 17-3325                                                      9

contends that the judge should have explicitly accepted or re-
jected Dr. Sageman’s conclusions about his risk of recidivism
or explained their effect. Not so. Tounisi used Dr. Sageman’s
conclusions throughout his presentation to support his views
on the § 3553(a) factors, and the district judge addressed each
of those arguments. Thus, even though the judge did not
orally state his view of Dr. Sageman’s conclusions, he consid-
ered the primary subject of the report, and a need for specific
deterrence did not figure heavily, if at all, in his selection of a
maximum sentence. It is clear, though, that general deterrence
did play a role in the judge’s decision—he concluded that “a
great need for general deterrence” existed and explained
why.
     Second, Tounisi maintains that the judge erred by failing
to explain why a shorter sentence would not suffice, relying
on United States v. Ferguson, 831 F.3d 850 (7th Cir. 2016). But
in Ferguson the district court had ignored both parties’ sen-
tencing recommendations and imposed a sentence more than
two-and-a-half times longer than the high end of that guide-
line range without justifying the choice. Id. at 854–55. In con-
cluding that more explanation was needed, we relied on the
Supreme Court’s admonishment that a “major departure” re-
quires “a more significant justification than a minor one.”
Id. at 854 (quoting Gall v. United States, 552 U.S. 38, 50 (2007)).
Here the judge chose the guideline sentence of 180 months, so
it follows that an extended explanation of why he did not pick
a lower sentence was unnecessary. See United States v. Kappes,
782 F.3d 828, 864 (7th Cir. 2015). Still the judge more than ful-
filled his obligation to explain the chosen sentence: he care-
fully covered every § 3553(a) factor and addressed each of
Tounisi’s mitigating arguments.
10                                                  No. 17-3325

    Third, Tounisi argues that the judge improperly weighed
several § 3553(a) factors. The government asserts that these
are actually disputes with the sentence’s substantive reasona-
bleness, not procedural arguments, but Tounisi persists in
calling them “procedural” in his reply brief. We agree with
the government that Tounisi is challenging the substance of
the district judge’s decision, see United States v. Warner,
792 F.3d 847, 856 (7th Cir. 2015), but his arguments are merit-
less either way. He confusingly contends that the judge erred
in finding a need to promote respect for the law by focusing
solely on the offense conduct. Tounisi points to his remorse,
honesty with the government, and desire to help others avoid
the same path to show that he respects the law. He never
made that argument at sentencing, though, and even if he
had, it does not defeat the judge’s concerns about Tounisi’s
persistence in joining a terrorist group and his lies to the FBI.
    Tounisi also asserts that the judge placed the seriousness
of the offense above all other factors, thereby disregarding
him as an individual and implying that all defendants con-
victed of a “terrorism” offense would warrant the maximum
sentence. But the judge consistently referred to the circum-
stances of Tounisi’s case, including that he had carefully
planned the offense, ignored his parents’ wishes, knowingly
sought to join a terrorist group, and risked being turned
against the United States. The judge made it clear that he con-
sidered the offense serious not just because it was a terrorism
offense but because of how Tounisi committed it and the
damage he could have foreseeably caused.
   Last, Tounisi argues that the district judge did not suffi-
ciently justify the lifetime term of supervised release. (At oral
No. 17-3325                                                  11

argument, Tounisi’s counsel clarified that he does not chal-
lenge any of the supervised-release conditions on appeal.)
Tounisi points out that he contested the length of the recom-
mended term of supervised release in his sentencing filings,
yet the district judge did not specifically address the parties’
divergent proposals, except to say that he had considered the
§ 3553(a) factors. Tounisi cites a case in which we remanded
the defendant’s sentence so that the district court could con-
sider the defendant’s “serious arguments” about supervised
release and “the interaction between the length and terms of
supervised release.” United States v. Quinn, 698 F.3d 651, 652
(7th Cir. 2012).
    Although Tounisi undoubtedly preserved his argument
about the length of supervised release, we cannot say that he
prioritized it at sentencing. He requested a 10-year term twice
in filings, but counsel never mentioned that request during
the sentencing hearing. These two written comments about
supervised-release length are unlike the “serious arguments”
made in Quinn and instead are more like those we character-
ized as not even “principal” arguments in Kappes. See 782 F.3d
at 846–47. There, a defendant’s counsel requested 10 years of
supervised release just once at the end of oral remarks during
sentencing. See id.
    As we did in Kappes, we conclude that, without any par-
ticular emphasis on the supervised-release term, the judge
was not obligated to explain it at length. Id. at 847. His deci-
sion to discuss his “reasons for imposing the sentence as a
whole” was “a reasonable choice.” Id. Supervised release and
prison are part of “a single sentence,” and therefore just “one
overarching explanation and justification—tethered, of
course, to the § 3553(a) factors”—is required. United States v.
12                                                 No. 17-3325

Oliver, 873 F.3d 601, 610–11 (7th Cir. 2017) (internal citation
omitted); see also United States v. Moose, 893 F.3d 951, 960
(7th Cir. 2018). A district judge is not required to rehash the
relevant factors after he has just discussed them as they relate
to an appropriate imprisonment term. See Oliver, 873 F.3d at
611. The judge in this case carefully reviewed the § 3553(a)
factors when he explained the prison sentence, so repeating
his explanation in the supervised-release context was in no
way required, especially since he chose a term within the
range suggested by the policy statements.
    Tounisi emphasizes, however, that the factors that may be
considered for purposes of determining the term of super-
vised release are slightly different than the § 3553(a) factors.
The relevant statute for supervised release, 18 U.S.C.
§ 3583(c), instructs a district judge to consider the factors
listed in § 3553(a), except for “the need for the sentence im-
posed” “to reflect the seriousness of the offense, to promote
respect for the law, and to provide just punishment,”
§ 3553(a)(2)(A), and “the kinds of sentences available,”
§ 3553(a)(3). Thus, Tounisi maintains that the judge placed the
offense’s seriousness above all else, so the justification given
for the imprisonment term cannot support the chosen super-
vised-release term. But Tounisi misunderstands the judge’s
reasoning. The judge permissibly considered “the nature and
circumstances of the offense,” 18 U.S.C. § 3553(a)(1), in deter-
mining both the appropriate terms of imprisonment and su-
pervised release. The discussion of that sentencing factor, just
like the discussion of the offense’s seriousness, was just one
part of an extensive explanation for the sentence imposed.
     For the foregoing reasons, we AFFIRM the judgment.
