Commanders of Iran's elite Islamic Revolutionary Guard Corps (IRGC) drank tea, nibbled dates and displayed models of Iranian missiles at a defence show in Qatar, a Gulf Arab state that is home to the largest U.S. military base in the region.
Their presence was striking when other Sunni Muslim Gulf states and Israel are alarmed at the prospect of the United States removing its terrorist designation of the IRGC as part of efforts to revive a nuclear pact with Iran.
