I’m amazed at the number of people who think Russia’s problem is a good thing. It is absolutely frightening. The analogy of a wounded bear is very appropriate here. If Obama goes through with the latest set of sanctions, Putin will be forced to react. I agree with Whirlybird that they have neither the money and definitely not the time to counter attack, unless they can convince the other members of BRICS to help them.
With the Chinese economy starting to falter they may be inclined to help Russia economically. Read in another post that with the cheap price of oil, that China is starting to stockpile.
A very volatile situation, that could turn a cold war into a hot war.
