The US and its Junior Partner have never lost faith in capitalism.Most of the balls up in the middle east was cause by America (With some help from the UK).
The Iranian situation was caused by America removing the elected government and replacing it with a dictator.
The Iraqi situation when America put Saddam into power.
Egypt when America installed it's personal dictator.
Israel when America supported the almost defeated Israel as part of its cold war messing about, and so on.
America complains about terrorism but is a far worse offender than anyone that has attacked it.
Since you can't have capitalism without imperialism, elites in both corporate states have no choice but to continue instigating wars of choice far from their homelands. Should the US Petrodollar collapse, it won't be possible to continue borrowing enough money to kill millions of innocent Muslims on the other side of the planet; bad news for millions of Mexicans, I suspect.
