I didn't mean to imply that a treaty cannot be broken, but I think it would be incredibly poor judgement to do it unilaterally.   It would create mistrust  with any nation that had wanted/needed the US as co-signer.   You and I are both in the 'reform' category, but it takes some real wisdom to pick and chose your battles.   I don't rate the administration as fully function, (more the gang that couldn't shoot straight), but maybe with more experience they develop some consistency.    I'm not optimistic with our ADD President who has trouble staying focused through a full sentence.    Rational conservative could overcome him but he's too vain to relinquish  his authority, or, to even trust subordinates.   "I know they took the strawberries, dangerous miutineers"
