The perception that Fallon has opposed a drive toward military action against Iran from within the Bush administration dates to his confirmation hearings in January 2007, when he told the Senate that the United States needed to exhaust all diplomatic options in its disputes with the Islamic republic. But he also has said that the United States would be able to take steps if Tehran were to attempt to block the Strait of Hormuz, the outlet of the Persian Gulf and a choke point for much of the world's oil. And he recently told CNN that the United States is looking for a peaceful settlement to disputes in every case. "We're trying to encourage dialogue and find resolution," he said. "In fact, that's our message to the Iranians out here, given that everybody is nervous and anxious about their activities, is to come forth and explain what they are doing with all the people in the region." Senate Majority Leader Harry Reid said Fallon's resignation showed that independent views "are not welcomed in this administration." "It is also a sign that the administration is blind to the growing costs and consequences of the Iraq war, which has so damaged America's security interests in the Middle East and beyond," said Reid, D-Nevada. "Democrats will continue to examine these matters very closely in the coming weeks and months." Admiral Fallon is also understood to have been pressing for a greater allocation of troops to Afghanistan, but has been frustrated at the reluctance of the Administration — and General Petraeus — to withdraw significant numbers from Iraq in the short term.
