Obama Must Defend NATO's Red Lines From Putin's Aggression by Michael Barone
Last week, masked men in camouflage garb with no insignia, dressed and equipped like Russian special forces, started taking over police stations and other government buildings in the Donets basin in Eastern Ukraine. They appeared to be working in tandem with local militias in defying the Ukrainian government.
This week, the Ukrainian government has responded by sending in military forces to counter these actions. There has been shooting and violence. But Ukraine's military doesn't seem capable of asserting control.
