TL;DR
Iraq authorized the Popular Mobilization Forces to 'respond' to any threat — five days later, no attacks on US forces have occurred.
MSM Perspective
AP noted 'no incidents involving PMF forces' in its daily Iraq security brief.
X Perspective
X's Iraq watchers read the silence as strategic restraint, not absence of capability — the PMF is waiting for Iran's signal.
Iraq's Popular Mobilization Forces have not conducted any attacks on U.S. forces since the Iraqi government authorized them to "respond to any threat to national sovereignty" on March 22. Approximately 2,500 U.S. military personnel remain at bases in Iraq, including Al Asad and Erbil. [1]
The authorization remains active. The restraint may reflect Iranian strategic calculation — using the PMF authorization as leverage rather than deploying it as kinetic force.
