(NBC News) As NATO allies gathered in Wales Thursday, a breakthrough on Ukraine appears imminent.
Government forces and Russian rebels say they will cease-fire on Friday and agree to Russian President Vladimir Putin's peace plan that locks in recent gains by his forces.
Ukrainian President Petro Poroshenko, at the NATO meeting, is taking the best deal he can get.
"To do my best to stop the war," Poroshenko said.
Meanwhile, President Obama used side meetings at the summit to build a coalition for air strikes on ISIS bases in Syria.
Ground attacks on ISIS could come from Arab nations, though some American forces could be involved as well.
"You're going to have to be surgical in your strikes. That may involve our special operations forces, such as SEALs and the Delta force," notes Senator Bill Nelson
Aides say President Obama is not in a rush to settle on an ISIS strategy; he wants a multi-nation coalition.
