WASHINGTON, July 7 (UPI) -- Resolutions working their way through both houses of Congress would require a naval blockade to impose its draconian measures against Iran. Tehran’s military chiefs threatened “blitzkrieg” tactics if the Gulf (25 percent of the world’s daily oil supply) came under attack. But at the United Nations, Iran’s foreign minister talked compromise. Talk about talking appeared to be Iran’s way of muzzling talk about war.
