Defense officials have
said that weapons smuggled into Iraq by the Iranian regime have already resulted in the deaths of American troops. In June, 15 servicemen were killed in Iraq. The U.S. attributed all the attacks to militias trained by the IRGC.
Iranian officials have denied the role of the IRGC in arming militants in Iraq and Afghanistan, and have claimed the U.S. concocted these stories to justify maintaining an American military presence in the region.
