So you are saying that Col Warren would make a statement like this based on Twitter without having other evidence:
The Russian military fired artillery rounds into eastern Ukraine on Thursday, a clear escalation of hostilities there, Army Col. Steve Warren, a Pentagon spokesman, said.
Russia has about 12,000 troops on the border with Ukraine, Warren said. Russian tanks, artillery and rocket launchers have crossed into Ukraine to support separatists there.
This is a clear escalation, Warren said.
The Russians have conducted artillery attacks on Ukraine military targets for the last several days, Warren said.
The “Evidence” appears at this point to be some kid’s video on Facebook. I kid you not.
And it was just three days ago that the State Department spokeperson was saying that “much of what they know comes from Social Media”
Really?
And after everything Obama has done, we are just supposed to accept this stuff at face value now, on this one subject alone?
