Yes it could be done but the power vaccume we'd create would be worse. Or bad guys would win.
Ex: in Syria, Assad, a dictator, would prevail and everyone who fought for freedom would die for nothing.
In Afghanistan, the government would collapse and fragment groups of islamic based assholes would rip through everything and essentially make life hell for everyone instead of a few. Then they'd build up strength and hit us again as revenge.
What we need is not to build nations in our image, but to let them be built in theirs. Without the assholes.
