Iran is making lots of noise about closing the Strait of Hormuz, the vital international waterway that carries 17 million barrels of oil every day35 percent of the crude oil transported by sea. The control of the Persian Gulf region is in Irans hands, Iranian naval chief Habibollah Sayyari ominously warns. This follows news that the Iranian parliament is mulling legislation to block tanker traffic through the strait, which comes on the heels of Sayyaris boast late last year that closing the strait would be easier than drinking a glass of water.
