When it comes to power, the Bush administration has always firmly believed two things: first, the President should have more of it; and second, international institutions like the U.N. should have less of it. In that respect, the landmark ruling on U.S. treaty commitments handed down by the Supreme Court Tuesday seems to be both good news and bad news for Bush and his hard-line colleagues in the office of the Vice President. The court slammed the door on a provocative power-grab by the White House, but it also potentially undercut a whole category of treaties, in the process exposing America's weak system for complying with international law.
