Did you read about US behaviour to Iraq in the media?

Yesterday the US was reported to have threatened to freeze Iraq's oil revenues should pro-Iranian groups be included in the next government.

This week American troops finally left Iraqi government controlled territory, six years ago after Iraq asked the American and Iranian troops to leave, following the Americans assassinating Iranian commander Qasem Soleimani on his way to talks with the Iraqi government.

Trump ignored Iraq's request in 2020 and threatened to freeze $8 billion of Iraq's money in US banks if US troops were forced out. 

US troops remain in the autonomous region of Kurdistan. I do not know if this is legal.
