MANAMA, Bahrain --
Iran is trying to build a nuclear bomb, posing a threat to its neighbors, and the United States is "very ready" to counter Iran should it make a move, the top U.S. military officer said Saturday.
Adm. Mike Mullen, chairman of the Joint Chiefs of Staff, sought to reassure Persian Gulf nations nervous that an increasingly militarized government in Iran might try to start a war.
"The United States takes very seriously our security commitments in the Gulf region," Mullen said after a meeting with Bahrain's king. Bahrain, directly across the Gulf from Iran, is home to a large U.S. Navy base that would be on the front lines of any war with Iran.
"We're very ready," Mullen said, an unusually direct acknowledgment that the United States has contingency plans to counter Iran should it make a move. "There are real threats to peace and stability here, and we've made no secrets of our concerns about Iran."
In Iran, the new foreign minister — and current nuclear chief — said Saturday that he wants to build the country's relationship with Saudi Arabia and strengthen ties with Turkey, China and Russia. The latter two countries have veto power on the U.N. Security Council that could help Iran as it tries to fend off tougher sanctions.
Ali Akbar Salehi, who heads the Atomic Energy Organization of Iran, replaced longtime foreign minister Manouchehr Mottaki, who was fired Monday by President Mahmoud Ahmadinejad without public explanation.
Iran denies it is seeking a nuclear weapon, and denies U.S. claims that it sponsors terrorists.
"Concerns about Iran's nuclear program are very real and inform a lot of the decision making" among Gulf nations, said Adam Ereli, the U.S. ambassador in Bahrain.
The United States fears that if Iran masters the technical challenge of building a bomb it could set off a nuclear arms race around the Gulf.
"From my perspective I see Iran continuing on this path to develop nuclear weapons, and I believe that that development and achieving that goal would be very destabilizing to the region," Mullen said.
