The likely spillover of an expanding tit-for-tat between Israel and Iran into Iraq has left the Donald Trump administration nervous about sustaining a long-term US presence in the war-weary nation.
A suspected Israeli strike against an Iran-backed convoy crossing the border between Iraq and Syria on Sunday night prompted the Pentagon to rush out a rare statement denying American involvement. The attack on the convoy, which was en route to Damascus, Popular Mobilization Units (PMU) bases and ammunition dumps, killed nine Shiite militants.
