Just three years ago, Iraq was on the brink of expelling U.S. troops that had helped drive the Islamic State out of the country. In January 2020, days after a monthslong military tit-for-tat between the United States and Iran had culminated in the U.S. assassination of a notorious Iranian military commander and a retaliatory ballistic missile attack on U.S. troops in Iraq, the Iraqi parliament, with the backing of the then-caretaker prime minister, took a symbolic vote to kick out foreign forces.
The scene in Baghdad, according to former U.S. officials, was a state of near-pandemonium, with Iran-backed Hezbollah operatives whipping votes in a flurry of calls just as U.S. lawmakers would on Capitol Hill—only in this case, with much more serious carrots and sticks attached.
