Here he calls them stupid;
"And the plurality’s unsupportable contrary determination merely confirms that “‘the Judiciary has neither aptitude, facilities nor responsibility’” for making military or foreignaffairs judgments. Hamdi, 542 U. S., at 585 (THOMAS, J., dissenting) (quoting Chicago & Southern Air Lines, 333 U. S., at 111)."
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."
