Bear in mind, the US 'popularity meter' has gone down since the days of Clinton, and i personally and most people i know certainly disapprove of current American administration in almost every way. But there's:
A) An election coming up, then the guy is gone, *poff*
B) The American people can change their government and its policies by voting. (I certainly hope so in the next election), other bigger countries cannot.
C) Russia and China are the real future-threats. Middle-east is just their playground.
D) I am really happy that we have a superpower that we can freely mock and make fun of, without worrying about them trying to invade our country (see eastern Europe, Finland during the cold war)
E) For those that live in democratic countries, don't like the US policy? Vote in someone who is a critic about it, they are the extension of your will, use your power to do so. And for those in the US, do the same.
Blowing up civilians will never solve anything.
