ABOARD THE CHARLES DE GAULLE - Some Iraqi army units in line for U.S.-led training to fight the Islamic State group are showing up ill-prepared, the top American general said Sunday.

Gen. Martin Dempsey, speaking to reporters aboard this French aircraft carrier in the northern Persian Gulf not far from Iran's coast, said he sees no reason to send more U.S. military trainers or advisers at this time. More, broadly, he defended the pace of the overall military campaign in Iraq.

"Right now we don't need more advisers on the ground," Dempsey, chairman of the U.S. Joint Chiefs of Staff, said with his French counterpart, Gen. Pierre de Villiers, at his side on the hangar deck of the de Gaulle.

"We've got trainers and advisers that are waiting for some of the Iraqi units to show up, and when they've shown up - a handful of them - they've shown up understrength and sometimes without the proper equipment. The Iraqi government can actually fix that themselves."

The crux of the U.S.-led coalition's strategy for dislodging IS from Iraq is this: degrade the militants' fighting power and resources through limited airstrikes against positions in northern and western Iraq, as well as in Syria; train and advise underperforming Iraqi security forces; and press the Iraqi government to take firmer steps to reconcile with the disaffected Sunnis.

"This is going to require some strategic patience," Dempsey said.

He said the military part of the conflict could be concluded "in the foreseeable future." The underlying problems - failures in Iraqi governance and a disaffected Sunni population - probably will take longer to resolve.

Dempsey spent the day aboard the de Gaulle to highlight U.S.-French military cooperation and to discuss strategies for combating IS in Iraq. He planned to visit Iraq next to discuss the campaign with government leaders and U.S. military commanders.

France is flying a variety of missions into Iraq from aboard the de Gaulle, which began operating in the northern Gulf on Feb. 23 and is scheduled to remain for eight weeks.

Dempsey watched as four French Rafale attack aircraft roared off the carrier's deck en route to Iraq, and later he observed four Super Etendard fighters land after returning from a mission.

French officials said they are flying 12 to 15 missions a day, including intelligence and surveillance flights, airstrikes and close air support missions in coordination with Iraq ground troops. Dempsey said that makes the French a valued partner in a conflict that has about 20 countries flying various air missions but only three conducting maritime operations.
