Do you not think asking a populace to pay to remove troops with their own taxes when everyone in that country likely knows someone who died is a low move? How many bases does one empire need? 800? 900?
America owes Iraq and not the other way round. They lied to start the war, had no legal authority and even here Trump again had no legal right to do what he just did. It was a violation of international law.
Same in Syria with the faked up chemical attack. That was an illegal act of war.
Trump with the drones has continued what Obama was doing.
These policies will enrage more and continue the wars indefinitely.
America has a terrible track record of wasting trillions on war whilst accumulating debt and having orange people on TV pretend the economy is booming. It is more fragile than you think. This is all about the petrodollar.
