We were pretty good with nation building if that's the right word with Germany and Japan after WWII and South Korea after the Korean War. But those countries had been countries long before each war. The tribal aspect wasn't there. Germans viewed themselves as Germans, The Japanese as Japanese and Koreans as Koreans.All three of those countries faced an outside threat in the USSR first, then Red China second which also help unify those countries and make nation building a success.

The Vietnamese also viewed themselves as Vietnamese for the most part with the Montagnards being the exception, viewing themselves more tribal. But with the Vietnamese, it was a fight for independence from Colonial Masters, then the Japanese occupation and once again the French after WWII.

Iraq still is a problem. But we still have troops stationed there. So nation building in Iraq seems to have worked, at least so far. But a month ago, one probably could have said the same for Afghanistan.

It's high past time that we start electing Americans to congress and the presidency who put America first instead of their political party. For way too long we have been electing Republicans and Democrats who happen to be Americans instead of Americans who happen to be Republicans and Democrats.
