So I think the Iraqi parliament is meeting this week. The Iraqi Prime Minister was among those paying respects with the mourners of Soleimani.
Best guess, Iraqi’s parliament at a minimum proposes a timeline for US troops to leave the country and Trump agrees against the wishes of the Neocons like Lindsay Graham and crew. He moves troops to Kuwait. Worst case, they ask him to withdraw immediately, but it will still take some time. I do believe Trump wants out and this gives him a way out of a sovereign country with honor.
Iran would be wise not to re-escalate if Iraq’s parliament asks us to leave, because one thing is sure, if they go on the attack we will retaliate in a big way.
Maybe I’m too hopeful.
