The bitter conflict in Ukraine drags on. Russia appears to have decided against trying to conquer its neighbor. However, Moscow continues to destabilize Kiev by supporting Russian separatists. NATO remains divided on how to respond.
Most Europeans have little stomach for confronting Russia. Economic ties with Moscow are profitable, there is no treaty obligation to Ukraine, and no alliance member desires war. So Washington has taken the lead against Moscow even though America has little at stake in Russia's misbehavior.
In fact, the crisis has generated a spate of U.S. proposals for military action. Some analysts and politicians advocate direct support for Ukraine and other potentially embattled states. Also popular are proposals to expand NATO.
