Jordan: US Forces Plan Shield Against Syria From the edge of a steep mountain overlooking a desert compound built into an old rock quarry, machine gunfire echoes just outside hangars where U.S. special operations forces are training Jordanian commandos. The Americans, who arrived in the kingdom a few weeks ago at the request of the Jordanians, are helping them develop techniques to protect civilians in case of a chemical attack from neighboring Syria, according to Jordanian officials. On the Syrian border farther north, British military officers recently assessed the dangers of rockets constantly falling on the kingdom and ways to shield the Jordanian population and Syrian refugees as President Bashar Assad widens his military offensive against rebel enclaves in the vicinity, according to Jordan-based Western diplomats. Jordan's King Abdullah II has repeatedly discussed plans for reinforcing security along the Syrian border and expressed concern over Syria's chemical stockpiles in meetings with visiting Western allies, according to the two diplomats, who monitor Syria from their base. They said it is believed that Abdullah has also been shopping around for an anti-missile defense system to shield his densely populated capital, Amman - home to nearly half of Jordan's population.

The fear is that those weapons might otherwise fall into the hands of al-Qaida or Lebanon's Islamic militant group Hezbollah. "There are dangers involved, and we have to ensure the safety of our country and the well-being of our citizens," a senior government official said in the first public Jordanian confirmation of the presence of foreign military personnel here. We are benefiting from the experience of our allies as we prepare for the worst scenarios. The presence of some 150 Americans at the King Abdullah II Special Operations Training Center northeast of the capital is a clear message to Assad that Jordan's longtime Western allies stand ready to defend the country if it is dragged into the 19-month Syria conflict. Assad's regime, which is believed to have one of the world's largest chemical weapons programs, has said it might use them against external threats but not against Syrians. But the Jordanians worry that Assad may use his chemical weapons against his neighbors, or his countrymen, if he felt that his days in power were numbered. In May, the U.S. held joint exercises with Jordan, nicknamed the "Eager Lion," which focused on the ways to deal with a chemical weapons attack. On Wednesday, U.S. Defense Secretary Leon Panetta said at a NATO conference of defense ministers in Brussels that the U.S. has been working with Jordan to monitor chemical and biological weapons sites in Syria and was helping Jordan deal with refugees pouring over the border. Although the senior government official insisted that the Americans were "advisers, not troops," two senior U.S. defense officials said most were Army special operations forces. The U.S. officials spoke on condition of anonymity because they were not authorized to comment publicly about the mission. The troops are operating out of a military center near Amman and have moved back and forth to the Syrian border. Their work involves gathering intelligence and planning joint Jordanian-U.S. military maneuvers, one U.S. official said.
