We know from what happened to Georgia that when Russian leaders say the following, they are preparing to invade:
“We do not understand what is going on there. There is a real threat to our interests and to the lives of our citizens,” Medvedev was quoted by Russian news agencies as saying.
This is a long-standing tradition that goes back to Stalin’s times. Any invasion of any country is justified if Russia perceives that country as a threat. No evidence that the threat is real is ever needed.
At this point, the probability is extremely high that Russia will use the ousting of the corrupt President Yanukovich by the citizens of Ukraine as an excuse to claim feeling threatened and invade. When Putin invaded Georgia in the same way in 2008, nobody in the West made as much as a peep (except John McCain who was running for president and made a very strong and important statement). This is telling Putin that nobody will do anything to defend Ukraine either.
Will the world stand mutely by as Putin invades Ukraine and annexes parts of the country?
