Here he calls them Dangerous:
"After seeing the plurality overturn longstanding precedents in order to seize jurisdiction over this case, ante, at 2–4 (SCALIA, J., dissenting), and after seeing them disregard the clear prudential counsel that they abstain in these circumstances from using equitable powers, ante, at 19–24, it is no surprise to see them go on to overrule one after another of the President’s judgments pertaining to the conduct of an ongoing war. Those Justices who today disregard the commander-in-chief’s wartime decisions, only 10 days ago deferred to the judgment of the Corps ofEngineers with regard to a matter much more within the competence of lawyers, upholding that agency’s wildly implausible conclusion that a storm drain is a tributary of the waters of the United States. See Rapanos v. United States, 547 U. S. ___(2006). It goes without saying thatthere is much more at stake here than storm drains. The plurality’s willingness to second-guess the determination of the political branches that these conspirators must be brought to justice is both unprecedented and dangerous."
Here Thomas destroys the Geneva Convention Argument
"In any event, the Court’s argument is too clever by half. The judicial nonenforceability of the Geneva Conventions derives from the fact that those Conventions have exclusive enforcement mechanisms, see Eisentrager, supra, at 789, n. 14, and this, too, is part of the law of war. The Court’s position thus rests on the assumption that Article 21’s reference to the “laws of war” selectively incorporates only those aspects of the Geneva Conventions that the Court finds convenient, namely, the substantive requirements of Common Article 3, and not those aspects of the Conventions that the Court, for whatever reason, disfavors, namely the Conventions’ exclusive diplomatic enforcement scheme. The Court provides no account of why the partial incorporation of the Geneva Conventions should extend only so far—and no further—because none is available beyond its evident preference to adjudicate those matters that the law of war, through the Geneva Conventions, consigns exclusively to the political branches."
