The commander of US naval forces in the Persian Gulf says the Navy and its Gulf allies won't let Iran seal off the strategic Strait of Hormuz. Vice Adm. Kevin Cosgriff, commander of the 5th Fleet, and Gulf naval commanders are discussing the region's maritime security, trade routes security and terrorism threat at a conference in Abu Dhabi. The 5th Fleet is based in Bahrain, across the Gulf from Iran. Cosgriff said that if Iran chocked off the Strait of Hormuz, it would be "saying to the world that 40 percent of oil is now held hostage by a single country." Cosgriff said: "We will not allow Iran to close it." His comments follow Iranian threats to seal off the key oil passageway in case of a Western attack on Teheran.
