In fact, if you read the inter-American weapons treaty that Obama wants the Senate to ratify, it spells out explicitly that it is limited by the Constitution of ratifying states. Moreover the US Constitution prohibits international treaty from abrogating US Constitutional law. The Senate can abrogate or vacate an international treaty with the same 2/3rds vote that is required to ratify.
I don’t understand your subsequent post, which I presume is sarcasm, so I’ll stick with this one. Honest question: which Constitutional provisions do the Torture Convention and Geneva Conventions abrogate? Like I said, I think we should pull out of those treaties, but if they are made moot by the Constitution, then it doesn’t matter.
