A man walks past a poster of senior Iranian commander Qasem Soleimani in downtown Tehran, Iran, on Jan. 5, 2020. The latest confrontation between Tehran and Washington on Jan. 3, which led to the killing of Qassem Soleimani, commander of the Quds Force of Iran's Islamic Revolution Guards Corps (IRGC), has nurtured a risk that could lead to a war.
