Leaving the 'personal' insults aside SASLess (I'm not sure it is possible to be personal on an anonymous internet chat forum), I do have to agree with you that President Obama (as an American, you should really show more respect for that office, notwithstanding your almost rabid levels of antipathy towards its incumbent) has been somewhat disappointing in his lack of leadership on Ukraine, but my point about Bush Snr was that a failure in moral leadership isn't the reserve of Democrat presidents.
As to 'peace in our time', some might say we went some way to exercising that particular stain on our national conscience by honouring our treaty obligations with Poland and declaring war on Germany on their behalf. Perhaps that wasn't in our self interest SASLess, but the world is a better place that we did. Maybe there's a lesson there.
