As the US pulls its forces out of Iraq, what happens to Iran-backed armed groups?

The United States has announced the withdrawal of its military forces from Iraq, 23 years after the 2003 invasion that overthrew Saddam Hussein. The development has been formally hailed by the Iraqi government as a final return to national sovereignty.

Simultaneously, powerful Iran-backed armed groups and members of Iraq's pro-Iran paramilitaries are celebrating the announced US departure. In response to the shifting security landscape, the Iraqi government has established a new deadline requiring these militias to integrate and disarm.
