Ukraine was plunged into civil war the minute their democratically-elected government was overthrown by a mob. It was "our" mob, of course, sympathetic to the West, so our media and leaders all cheered. But many in Ukraine, particularly the East, are far better off financially under Russian influence than they would be if Ukraine became another poor Eastern country in the EU.
This is a true civil war between East and West Ukraine. Just another indication of the chaos that happens when governments fall. When will we learn not to cheer for regime change in parts of the world we don't understand?
