Going into their NATO summit in Wales on Thursday, Western leaders are focusing on a failed policy in Ukraine. And so far, they lack a plan to reverse Russia's aggressive moves to bolster separatists' hold on eastern Ukraine.
Just two weeks ago, Ukrainian troops appeared poised to wrap up a military offensive against Russian-backed separatists who'd been fighting an insurgency since April. But the Ukrainian gains were soon reversed as Russia ignored Western economic sanctions aimed at deterring its backing for the separatists and instead poured military support into the rebel cause, according to the Ukraine government and NATO.
