Perhaps Trump will end the Bush folly. Our being in Iraq was at best idiotic. And so much done during the Bush Administration was in direct violation of federal law, the award of many billions in contracts with ZERO competition. And who was the recipient of these contracts? HALLIBURTON, where Dick Cheney had been a long time CEO. That whole nonsense disgusted me, and rendered anything Bush attempted to be corrupt.
I say pull out completely, and take EVERY piece of equipment. That includes every piece of equipment their military is using too. And rather than sanctions, I suggest reparations. Let Iraq pay for EVERY item used in the war effort there. And until we are paid in full, we control their oil industry completely, taking a cut right off the top with every transaction.
Fact is, the USA lost control of Iraq when Obama allowed Iran in to help fight ISIS. Both countries have Shia majorities, and so it is expected they would align with one another over any relationship with the USA or non muslim nation.
The combined folly of Bush and Obama will not be accurately told for some years, but the combined efforts of both presidents will be noted in history for a colossal cluster (*&^. So much blood and treasury spilled on two nations that would gladly see the USA destroyed(Iraq and Afghanistan).
Sooner we are out the better. Same for Afghanistan.
