I'm not so sure of that but you may be correct. The reason I say this is because a day or so before that I wondered why Russia had not yet come out with such a counter.
I think it's possible that Russia had this idea up their sleeve for some time during the whole crisis and I don't think it was shared with Obama during the meetings in Europe.
If such a thing had crossed my mind then surely it had crossed the minds of Putin and other world leaders (except Obama who was blinded by his desire to give radical islam another country).
did you see post #67?
