So all we need to do is have a war in Haiti, Africa, and any other shithole that needs upgrading?
Sad to say, but that's not far off the mark.
In WWII we killed or incapacitated the enemy, imposed our will and restructured their economies.
Look at Germany (up until the last few years). Look at Japan. Even South Korea.
The "let them restore their own order" peacenik nonsense doesn't work. If we want to solve the problem in the Middle East? Unleash our great vengeance and furious anger on those who attempt to poison and destroy our brothers. Eliminate the caliphate, put in a western government by military occupation, prove that the American way of life (or what it used to be) will allow the people to live and prosper in safety and security. Then and only then will the people take care of perpetuating it. All of a sudden we've got oil-rich allies.
Want to handle North Korea? Quit threatening the chubby bastard. Ramp up and take his ass out. Military occupation until the people take control.
I've moved firmly into the kill 'em all camp.
