A Lebanese Hezbollah official said the response of the Iran-backed “axis of resistance” to the killing of Iran’s military commander Qassem Soleimani in a U.S. air strike will be decisive, al-Mayadeen TV said on Saturday.

Terrorist group ISIS will likely be the winner as tensions between Washington and Tehran mount after the U.S. killing of Iran’s most powerful military commander, experts say.

The American assassination of a top Iranian commander may make it impossible for American forces to stay in Iraq. That could ease an ISIS comeback.
