The congress has to ratify treaties. He wants to sign,,, fine,, then Palin can take us to war to get out of it if she has to. A treaty is only as good as the army that enforces it.
This is a concept lost on the ignorant and the stupid.
The are no "good" or "bad" nations. The only ones that matter are the ones with the means to enforce their position, good or bad.
That should be obvious to even the densest delusion touchie-feelie type.
As a corollary, countries don't have friends or enemies; just interests.
Sure all of Europe could rise up and attack the US. To that I can only say...
Give it your best shot!
