President Obama on ISIS Fight: 'We Don't Yet Have a Complete Strategy'

The two men on the sidelines of the G7 Summit Monday.

— -- Ten months since the start of the American-led intervention against ISIS in Iraq, President Obama said today that the United States does not have a "complete strategy" to defeat ISIS and stem the group's rise in Syria and Iraq.

"We don't yet have a complete strategy," Obama said at the G7 summit of world leaders in Germany. "The details of that are not yet worked out."

Obama said he will announce a proposal for escalating the speed and scale of the training of Iraqi forces "when a finalized plan is presented to me by the Pentagon." He said the Iraqis still have to make commitments to make the strategy complete.

The president's comments echoed a statement he made last August shortly after U.S.-led airstrikes against ISIS first began.

“We don’t have a strategy yet," the president said. This came in response to a question whether he would seek congressional approval for the military campaign against ISIS.

Ten months later, the administration's plan to combat ISIS is under fire as the Islamic state has secured victories in Iraq and Syria.

“I’m confident that although it is going to take time and there will be setbacks and lessons learned, that we are going to be successful, ISIL is going to be drive out of Iraq, and ultimately it is going to be defeated,” the president said in the meeting.

“Undoubtedly, we will win the war,” Abadi said.

The three leaders eventually stood up, prompting Abadi to stand as well. Unrecognized by the leaders involved in conversation, Abadi looked at his watch as his translator lifted his hands in the air and eventually walked away.
