After the United States kills Iranian General Qasem Soleimani in the 2020 Baghdad International Airport airstrike, Iran's parliament votes to exit the 2015 Joint Comprehensive Plan of Action nuclear deal with world powers. This comes after the United States unilaterally withdrew in 2018.
In response to the death of Qasem Soleimani, U.S. President Donald Trump tweets an image of an American flag. He later defends the airstrike, claiming Soleimani "was both hated and feared" in Iran and "should have been taken out many years ago."
Iraqi Prime Minister Adil Abdul-Mahdi signs a decree ordering all Iranian-backed Shia militias to integrate into the Iraqi Armed Forces by the end of July. The decree will change the names of the militias such as the Popular Mobilization Forces to new divisions and brigades within the military.
