America, under Bush Jr, decided to topple the only completely stable Middle East country, where Al Quaeda had no presence whatsoever, aided by his sycophantic buddy Tony Blair.
Like him or not, Saddam Hussein had total control of Iraq, and was a stabilising influence/threat to Syria and Iran. Look at the entire area now.
Then, when Islaamic fanatics of Al Quaeda, based in Saudi Arabia, unleashed the dreadful 9/11 attacks, how did the US react? By invading a wild, tribal country called Afghanistan, that had had nothing to do with it!
Far more logical would have been to invade Saudi Arabia - but that would have upset too many rich people.
Now, 20 years and thousands of dead soldiers later, the US is in ignominious retreat.
In neither invasion did the US try to establish industries and commerce, whereby vested interest creates stability. Instead money was poured into "dubious" security businesses and the pockets of corrupt political leaders.
By contrast, look at the stability of South Korea, where the US poured money into enterprise.
It now has world leading companies like Samsung, to mention just one in a plethora of them covering electronics, automobiles, telecommunications, shipbuilding, chemicals, and steel.
