Your move, West.

This week, following the Ukrainian government's statement about trying to take back official (gov't, police) buildings in east Ukraine,  Russian foreign minister Sergey Lavrov answered with a simple, yet frightening, statement. In his words, Russia would mount a firm response if its citizens or interests come under attack in Ukraine. While not officially stating that Russia is going to proceed with military operations, this conclusion is fairly easily made. Especially knowing that thousands of Russian soldiers are massed along the Russian/Ukrainian border. This statement makes Ukrainian officials believe that Russia is simply setting up a trap for them to fall into, by forcing acts to happen that would give them the "right" to invade.
