Supreme Court out of control?

I have been reading Scalia's and Thomas's dissents in Hamdan v. Rumsfeld, and they are quite devastating. The liberals on the court not only seem to have completely ignored Congress's legislation on the court's jurisdiction, but the court ignores the President's war making powers and rely on international law. Good thing the Justices are there to set the congress and the president straight. Could you imagine the congress actually fulfilling their constitutional role to say what types of cases the courts can hear? Fortunately, we have five Justices who are competent to rewrite the laws and enter into the right foreign treaties when the congress and president ignore the obvious things that they should be doing.
