Allow me to speak in defense of Dubya's legacy, and of the war in Iraq.
The mission was and is clear: expel Al Qaeda from the country, and now ISIS. If we had learned anything from how to fight counterinsurgency in Vietnam, the execution would have been as well.
It wasn't mindless "jingoism" as you say, it was colossal mismanagement from the top down that cost lives of our troops and Iraqi citizens. It's a good example for not having military tactics dictated by think-tanks and bureaucracy. Not to mention personal interests in the higher echelons like Cheny's corrupt pet security firm.
The jingoism was just a cover more than anything. Strap enough flags to something, and certain demographics would go nuts for it, even if it was something fucking terrible like a King Cobra.
If we are to insist on being a global superpower (a largely dead term since the end of the Cold War) let us atleast push more diplomatic solutions, humanitarian aid can be a very useful if managed more rigourously. I would be much happier if most refugee camps were set up in places like inner Jordan. A place to stay while not being thrown into an inverted culture. Beats having them drown by the hundreds and sure as shit beats Merklestan.
As I mentioned, NATO's efforts have helped us in stamping out pirates in Somalia, as well as giving America and her allies irreplacible access to so many regions.
Kuwait especially deserves praise because of our naval base is critical for maintaining control of the Persian Gulf, and in our joint military exercises with the Kuwaiti military. Unlike our "friends" in the Saudi Kingdom (or most of the Middle East), Kuwait has a very secular court system that uses Shariah only in family law for Muslims, and it actually shows, considering the last execution was in 2013 for murder. It does have censorship of internet, mostly porn, but the state doesn't crack down on non-Muslim's private worship. I think they're the only nation in the region that even recognizes non-Muslims as citizens.
@Ntwadumela can probably give us a better perspective.
But if you want proof our current alliance system is fucked, look at what Saudi Arabia is like and conpare it to Kuwait. Beside the corruption and human trafficking for manual labor, they the closest thing to a truatworthy nation, at least one that isn't exporting Wahabbist horseshit through the Middle East that is a big reason these jihadists and Islamists keep fucking appearing every couple of years. If you cut the legs out from under the Saudis and Iranians, in a few generations of crushing any remaining Islamist holdouts, there would not be as many Islamists and very few jihadists if they had no access to the funds and gear they do now. We fucking did it twice to the north African territories of the fucking Ottoman Empire back in the early 1800's.
