Cut and pasted the following from an article re talk of Iraq kicking out US for carrying out assassinations on it's soil.

Iraq should brace itself for sanctions that'll make the ones placed on Iran look pale in comparison if it kicks out the US troops without first covering the costs the US spent on its airbase there, US President Donald Trump said.
“We have a very extraordinarily expensive air base that’s there. It cost billions of dollars to build, long before my time. We’re not leaving unless they pay us back for it," Trump told reporters on board of the Air Force One on Sunday.
The punitive measures that the US is ready to slap on its supposed ally in the fight against the Islamic State (IS, formerly ISIS) will be even harsher than the crippling sanctions already in effect against Tehran, the US leader said.
"If they do ask us to leave, if we don’t do it in a very friendly basis, we will charge them sanctions like they’ve never seen before ever. It’ll make Iranian sanctions look somewhat tame.”

Now if I was Iraq, it would be "fuck off dickhead. What are you going to do? Invade and destroy our country if we don't payup?"
