As Joshua Landis has tweeted today, “In response to Kerry’s demand Hizb & Shi’ite Iraqi militias leave Syria or be targeted, Iraqi militias threaten to hit US embassy with missiles.”
Many factors come into play here.

A few US air strikes on Alasaib Ahl al Haq or Kata’ib Hezbollah in Syria could trickle violence back on American interests in Iraq, intensifying the proxy war with Iran.
