However, with respect to Viet Nam and a few other places, we did indeed leave a few, relatively speaking, people in bad straits. Certainly not millions by any stretch. For some the error was their own and for some the fault was ours. That or the actually rather small numbers don'tt excuse those that we left that we should not have but the entire issue should be viewed in context and perspective. The vast majority of residents in Viet Nam and elsewhere were just thankful that we were gone and accepted the cost of those 'left behind.'

I suspect the same attitude prevails in Afghanistan. To cite promises presumed is irrelevant to all but those who wish for whatever reason to make an issue of them. Some here or there may feel "lesser." That as they say, is their problem. For the US, 'lesser' is a fact of life and has been for over a hundred years. TR started us on the downhill slope and W. Wilson accelerated the decline -- been going on ever since; generally at the hands of those in positions of power who were concerned with 'doing good.' That includes G. W. Bush who kept us in Afghanistan and Iraq, both places where we had no real business to cause us to stay because he -- not the Nation -- had an attack of sadly misplaced moral rectitude. IMO, he failed in his responsibility in his elected position because he put personal feelings before the good of the nation that he was nominally responsible for 'leading' (as if anyone could 'lead' the US... ).

As for perfidy, that's a feature of nations (plural as JMA noted), not a bug. Not going away, either. "Live with it..." Indeed.
