The issue the letter adresses is that politics, according to Galbraith, is a choice between bad and worse.  You, instead, use it to advance your unfavorable opinion about two specific politicians, both of whom are far more cautious, diplomacy-wise, than most of their forebears in high office.  Obama has used diplomacy wherever possible.  If you want an isolationist USA, you will, by necessity, have to be disappointed.  There is no possible president who can deal with all international problems in ways that won't leave some people angry and disappointed, both in our nation and outside of it.
