We pulled out of Iraq, as people wanted us to do, and then once ISIS shows up everyone gets mad at the U.S for pulling out too soon.
I doubt anyone got mad at the US for leaving Irak. As a matter of fact, most didn't want you to go there in the first place. People get mad at you for breaking countries and then not bother to fix your mess, and then claim you saved the day. Anyhow, Kudos to Bush for having started the hole Irak mess.
will non-Americans ever support any decision America makes?
I support any action that isn't dumb and ill-thinked.
Foreign policy Obama did good in his negotiations with Cuba, Iran and the anti-ISIS coalition. He did awfully in Syria, Lybia and Guantanamo. A good negotiator, but very poor jugement of the Arab Spring. Syria and Lybian meltdowns are on him + nato allies like France and UK.
So far Trump only took stupid foreign policy decisions, I'll support him if he makes a smart move, but that seems like an unlikely thing to happen in the forseable future, as he keeps taking the worse possible option every time.
