John Thomas Martin pleaded guilty to bombing a private dwelling, 18 U.S.C. § 844(i), and obstruction of justice. 26 U.S.C. § 5841. Martin appeals his conviction and sentence, arguing that (1) the impact of the bombing on interstate commerce was too slight to satisfy the interstate commerce requirement of § 844(i); and (2) the court wrongly calculated his base offense level under the Sentencing Guidelines, because he “merely” tried to damage, rather than destroy, the dwelling, and did not knowingly create a risk of death or serious bodily harm to the occupant of the house he bombed. We affirm.
I.
John Thomas Martin was divorced from his wife, Lynn Webster, and not happy about it. Before they separated, Martin told Webster that if she ever saw another man, he would kill the other man. Martin told his friends that he followed Webster around to see if she was seeing anyone. On September 14, 1995, Webster obtained a restraining order against Martin. Martin, however, continued to be obsessed with his ex-wife. He learned that Webster had been seen talking to a man who drove a black car. Thereupon, Martin tracked down the man’s identity, and learned that he and Webster worked together. The man in question was James Bowyer. Though Martin denies doing so, his eo-work-ers later told investigators that because he believed (falsely, as it turned out) that Bow-yer was dating Webster, Martin offered to pay them to beat up Bowyer, talked of blowing Bowyer up and also talked about setting off a bomb at Bowyer's house. In fact, Martin did more than talk: he brought a pipe bomb to work, and boasted that Webster was going to pay for cheating on him. The pipe bomb was just over five inches long and one- and-a-half inches in diameter.
On the night of October 5, 1995, Martin ran into his friend Martin Campton and informed Campton that he was going to bomb either Webster’s or Bowyer’s house. Martin *531 and Campton went to Bowyer’s house about 10:30 p.m. The house was dark, but Bowyer’s car- was in the driveway. According to Campton, Martin planted the pipe bomb at the back door of the house, and lit the fuse. Martin maintained that he set the bomb ten feet from the back door, after which Camp-ton detonated it. Bowyer was not injured in the ensuing explosion, but the bomb caused $4,000 in damage to the back door, the porch and a refrigerator on the porch, and another $3,500 in damage to a building behind Bow-yer’s house. Needless to say, it also roused Bowyer and his neighbors.
After fleeing the scene of the explosion, Martin called a friend from work, William Rabe, whom he met to work out an alibi. Martin gave Rabe the materials left over from constructing the pipe bomb, which Rabe subsequently destroyed. Martin also destroyed the shoes he had worn during the bombing and asked several other co-workers to lie about the incident to investigators.
The attempts to thwart the investigation were in vain. Campton cooperated with the government, which, with Campion’s consent, recorded a conversation between Martin and Campton about the bombing. In that conversation, Martin indicated that he made and detonated the bomb and believed he could face attempted murder charges as a result. Martin was arrested and indicted. He eventually pleaded guilty to one count of destruction of property by explosive, 18 U.S.C. § 844(i), 2 and one count of obstruction of justice. 26 U.S.C. § 5841. Martin stipulated that the bomb was set off to frighten Bow-yer. The plea agreement also stipulated that the utilities connected to Bowyer’s residence “affected commerce or moved in interstate commerce.” Martin disputed several of the factual findings in the Presentenee Investigation Report, including the Probation Office’s recommendation that his base offense level be calculated at 24, for knowingly attempting to harm Bowyer and destroy his house. The district court concluded that Martin planted the bomb himself, knowingly created a substantial risk of death or serious bodily injury to Bowyer when he did so and intended to destroy the dwelling. For those reasons, the court determined that Martin’s base offense level was 24, U.S.S.G. § 2K1.4(a)(l), and sentenced him to 108 months in prison, $7,396.50 in restitution and a term of supervised release. Martin appeals.
II.
The federal bombing statute requires that the damaged property be used in or affect interstate commerce. 18 U.S.C. § 844(i). Martin’s principal contention is that the residence which he bombed had too small an impact on interstate commerce to satisfy that requirement. Martin argues that under the Supreme Court’s decision in
United States v. Lopez,
Martin’s argument rests on the concept that a guilty plea does not waive jurisdictional defenses to the crime at issue.
United States v. Nash,
Relying on certain language in this court’s opinion in
United States v. Stillwell,
While we agree that defendants did not raise this issue at the district court level, defendants may raise this issue on appeal because it is jurisdictional. If the application of § 844(i) to defendants exceeds Congress’ power under the commerce clause, the district court could not exercise jurisdiction over the subject-matter contained in Count One (the arson conspiracy charge) and Count Two (the substantive arson charge). Lack of subject-matter jurisdiction, whether through statutory interpretation or constitutional prescription, is never waived.
Id.
at 1110 n. 2 (citations omitted);
see also United States v. Prevatte,
We acknowledge that the language in footnote 2 of
Stillwell
is mistaken and imprecisely states the basis on which this court permitted the defendants in that case to raise their argument for the first time on appeal. Accordingly, we take this opportunity to correct our explanation for allowing the defendants in
Stillwell
to challenge the interstate commerce element on appeal. We explain why
Stillwell
does not support a similar ground for appeal in the instant case. In
Stillwell,
the defendants had stipulated to certain facts regarding the house’s connections to interstate commerce, but argued on appeal that the connections to which they had stipulated did not satisfy the interstate commerce element of the statute. The defendants in
Stilkvell,
then, essentially argued that the indictment failed to state an offense. This argument was not presented to the district- court but the defendants claimed that it might be raised for the first time on appeal. Today we explain by way of clarification that review by this court for plain error was appropriate in that case despite the defendants’ failure to raise the argument on appeal.

United States v. Quintanilla,
Unlike in
Stillwell,
Martin has admitted every element of the offense by pleading guilty.
See United States v. Broce,
A defendant does not, according to recent Circuit precedent, “waive the right to contest whether [the] facts [which he admitted] are sufficient to constitute a crime,” when a change in the law changes the nature of the conduct deemed to be criminal.
Stanback v. United States,
III.
Martin also contends that the court should have calculated his base offense level at 20, not 24. The Sentencing Guidelines establish a base offense level of 20 if a bombing created a substantial risk of death or serious bodily injury to someone other than the bomber, or endangered a dwelling. U.S.S.G. § 2K1.4(a)(2)(A), (C). If the bomber knowingly created a substantial risk of death or serious bodily injury, or if the bombing involved the destruction or attempted destruction of a dwelling, the base offense level is 24. U.S.S.G. § 2K1.4(a)(l)(A)-(B). The sentencing court’s findings of fact are reviewed for clear error.
United States v. Hickok, 71
F.3d 992, 1007 (7th Cir.1996),
cert. denied,
Martin notes that the bombing damaged only the back door of the residence, part of the eaves and a refrigerator on the back *534 porch. Consequently, he maintains, he merely endangered the dwelling. Martin stipulated in the plea agreement that he set off the bomb in order to scare Bowyer. Because Martin wanted only to frighten Bowyer rather than hurt him; because the bomb was small, untested and placed at a back door rather than by a bedroom or living room; and because the government failed to prove that Martin knew Bowyer was in the house (which was completely dark at the time he set off the bomb); Martin reasons that there was insufficient evidence to establish that he either knowingly created a substantial risk of serious bodily harm to Bowyer, or was trying to destroy rather than simply to damage the house. As a result, he concludes that he is entitled to a base offense level of 20 under § 2K1.4(a)(2).
Unfortunately for Martin, the government provided a different version of events, and the sentencing court believed the government. The sentencing court’s credibility determinations are entitled to special deference. United
States v. Pippen,
But sentencing depends on proof by a preponderance of the evidence, not proof beyond a reasonable doubt.
United States v. Adams,
Under the language of § 2K1.4(a)(l), the inquiry is not whether Martin intended to harm his victim: it is whether Martin knew that his actions created a risk of harm.
United States v. Altier,
By pleading guilty, Martin admitted every element of the offense, including the effect on interstate commerce.
Broce,
Affirmed.
