Biden launched another retaliatory air attack on "Iran-backed militia groups" which seem to be using drones to bombard US military forces and US civilian activities in Iraq (for instance, a consulate). The Iraqi government condemned this attack.

It is the Iraqi government's responsibility to protect foreign consulates, and US forces as well if it has invited them to Iraq. This raises the question: why are the forces there?

Are they there to provide military support that Iraq wants? If so, Iraq should join in protecting them, including counterattacking if that is necessary.

But perhaps the Iraqi government regards US forces as intruders, and would rather they were gone. If so, removing them might be the right thing to do. The only force in the region that the US has a reason to fight is PISSI, as far as I know.
