U.S. Sanction Against Russia

U.S. sanction against Russia, and probably also the dropping of oil prices, got to be an economic, geopolitical and currency war of the U.S. against Russia.

Does sanction work? Yes and No, if you ask Obama. For Cuba, with whom the U.S. has just re-established diplomatic relationship, Obama said No. For Russia, Obama said Yes. If it didn't work on small Cuba, having been proved for more than 50 years, how would it be possible to work and hurt big Russia ? Mr. President Obama, please tell us ! 

U.S. sanction would hurt Russia and make it difficult for Putin for a while, yes, but not for a long time. It won't take 50 years or more, like in the case of Cuba, to find out. We'll wait and see. 

Sanction, in my opinion, largely hurts only the people - your own people, those of your allies, and those of the sanctioned country you try to hurt, but not so much the elites and governments in power. 

U.S. sanction against Russia has pushed Russia even closer to China. It hurts not only Russia, but also Europeans who do business with Russia. Maybe Germany, France and a few other European countries didn't really like the sanction against Russia, but wouldn't dare not to "obey" Uncle Sam, being under political pressure to follow.
