Very little of what the federal government does is actually constitutional, starting with the Supreme Soviet, er, I mean Federal Reserve as an example. Of course to decide to actually follow the constitution at this point would cause complete havoc, that's why there's a principle of stare decisis (yes, I watched the entire Robert Bork hearing). As far as foreign policy, what you have to realize is there are two overriding principles in foreign relations 1) Might makes right and 2) Whose ox got gored. You can whine and complain and bellyache all you want, but that's just a fact. The rest of the world is just lucky it's US that has the might right now, not a couple of other countries I can think of. If they did, you'd find out what murder, torture and repression really mean.
