More on this from Jon Karl traveling with president Obama at the nato summit in Wales and, Jon, the leaders stitching a coalition together to take on Isis. Reporter: That's right, George and Isis was not even originally on the agenda, but now it is front and center more than 50 heads of state here seeking a united threat against the threat and british prime minister David Cameron has taken a much tougher line than president Obama but this morning they are both on the same page literally here in the "Types" of London" a op-ed saying it's a barbaric threat saying they will not be cowed. Cameron this morning also said "Isis will be destroyed, squeezed out of exist tense," but, George, it's unclear what they are going to actually do here. What the strategy is beyond the current campaign of U.S. Air strikes in Iraq. Right, Cameron didn't rule out further air strikes. Cameron and Obama in that op-ed taking on Vladimir Putin saying he's trying to change the course of Ukraine from the barrel of a gun at the top of the agenda this morning perhaps more military and economic aid to Ukraine? Reporter: That's right. The prime minister of Ukraine was here meeting with the top nato leaders. They are talking -- he's requested, you know, more military assistance, more financial assistance, unclear exactly what nato is going to provide, but that is front and center here this morning. Okay, Jon Karl, thanks very much.
