US Navy buildup came after iran moves

U.S. Navy's Mideast Buildup Came After Iranian Provocations in Gulf, Navy Commander Says By JIM KRANE The Associated Press MANAMA, Bahrain - Iran has brought its war games maneuvers over the past year into busy shipping lanes in the Straits of Hormuz, the narrow mouth of the Persian Gulf through which two-fifths of the world's oil supplies pass, the top U.S. Navy commander in the Mideast said. The moves have alarmed U.S. officials about possible accidental confrontations that could boil over into war, and led to a recent build-up of Navy forces in the Gulf, Vice Adm. Patrick Walsh said in an interview with The Associated Press and other reporters. During maneuvers, Iranian sailors have loaded mines onto small minelaying boats and test-fired a Shahab-3 ballistic missile into international waters, he said. "The Shahab-3 most recently went into waters very close to the traffic separation scheme in the straits themselves. This gives us concern because innocent passage of vessels now is threatened," Walsh said in the interview Monday on the base of the Navy's Fifth Fleet in the Gulf island kingdom of Bahrain. Iran tested the Shahab during November maneuvers, which it said were in response to U.S. maneuvers in the Gulf it called "adventurist." Iran also showed off an array of new torpedoes in war games in April. The carrier USS John C. Stennis backed by a strike group with more than 6,500 sailors and Marines and with additional minesweeping ships arrived in the region Monday. It joined the carrier USS Dwight D. Eisenhower after President Bush ordered the build-up as a show of strength to Iran. The additional U.S. firepower has ratcheted up tensions with Iran. But Walsh said the increase aims to reassure Arab allies in the Gulf and prevent misunderstandings that could escalate into outright conflict. "That's certainly what we're trying to avoid, a mistake that then boils over into a war," said Walsh, who departs his command of the Fifth Fleet this month to become vice chief of naval operations at the Pentagon, the Navy's No. 2 post. Walsh said the Navy was responding to "more instability than we've seen in years" in the Fifth Fleet's region with conflicts in Iraq, Afghanistan and Somalia, tensions in Lebanon and the standoff with Iran. The Navy has grown increasingly alarmed at what Walsh called Iran's "provocations." Once cordial Navy ship-to-ship relations with Iran in the Gulf have disintegrated over the past 18 months as Iranian vessels made "probing" incursions into Iraqi waters, he said. "They threaten to use oil as a weapon. They threaten to close the Straits of Hormuz," Walsh said. "And so it is the combination of the rhetoric, the tone, and the aggressive exercises in very constrained waters that gives us concern." Since the Stennis was ordered to the region, Iranian leaders have increasingly warned that they would respond to any attack by closing off oil shipping lanes or attacking U.S. interests. The Straits of Hormuz are 34 miles across, but its shipping lanes are only about six miles wide. Walsh said it was doubtful that Iran could physically block the entire six-mile lanes with mines but hitting only a few vessels with missiles and mines would "terrorize" shipping and have the same effect. "It's more the threat of mines than the threat of closing the straits. That would have dramatic effects on markets around the world," he said. Walsh said his biggest worry was that Iran would underestimate U.S. resolve to protect its interests in the world's richest oil region. He said the tone of Iranian leaders could make their commanders on the ground more reckless. "It's a mix and a formulation where you can have misunderstanding," he said. Asked whether the U.S. Navy would launch an attack on Iran if Iranian involvement were confirmed in a deadly incident in Iraq, Walsh said he was unable to discuss the Navy's rules of engagement. But he added, "There are events on land that can spill over onto the sea." At the same time, Walsh said he understood that U.S.-allied Gulf nations feared that any U.S.-Iranian military conflict could bring attacks on their soil. Walsh said he was aware that a University of Maryland/Zogby International poll of Arab public opinion this month showed residents of the United Arab Emirates, Saudi Arabia and other allies believe Iran is far less a threat than the U.S. and Israel. "I'm trying to talk to those in the region, to give them assurances that the reason we're here is to stand by them," he said.
