Nations can withdraw from a treaty simply by giving notice, if there are nation specific actions beyond that to be processed internally that could vary, but if these clowns wrote this as a "human rights" treaty typically exclude withdrawal...I'm betting these clowns went that route. It is bad enough having an asshole regime like ours sign the rancid thing when big arms exporters like China & Russia are abstaining...any Senate ratifying this atrocity is declaring war upon us citizens and should be stormed by angry patriots.
