During the fall of 2019, major demonstrations broke out in the largest Iraqi cities, challenging both the Iraqi government and Iran. Meanwhile, several militias strove to counter the popular movement by heightening tensions against American interests. They conducted a wide range of operations: show of force, repression campaign, harassment of US military camps, etc. They proved extensive irregular warfare capabilities. Gradually, their actions scaled up and ended up prompting a massive reaction from Washington (elimination of General Soleimani). Against any odds, the assassination had favorable consequences for Iran: demonstrations lost their popular support and weakened, while Western military forces started pulling out. This huge strategic benefit may be a hint that these militias have been activated to carry out a sophisticated operation plan. Eventually, they engineered considerable outcomes from a rather weak initial investment. As such, they appear as a powerful tool of strategic leverage that can be activated remotely.
