Putin talked nice to the EU all day Thursday and after sundown sent his military convoy to aid [rearm] the separatists. These separatists are the same terrorists who used a Russian AA missile to down that airliner.
I bet this is only a part of a bigger plan Putin has worked out—what ever happens—it will happen quickly. This is an opening gambit—Putins Knights and Bishops are ready to strike the Ukrainians hard—with another unseen force ready to hit Keiv. It will be over in a week.
