The Russian federation is one of the influential country on the face of the planet aside from United States, so for anyone to feel like they will crack under sanction is really mistaken, their smart policy making have kept their economy strong even in the face of tough sanction, moreover sanction doesn't changes the mind of sanctioned regime, look at north korea, cuba, iran etc right now they are even getting worse instead of repenting, look at what is happening now, russia is uniting all the bad boys against the west, which is not a good thing, I just hope our leaders make some wise decision so we won't end up experiencing a nuclear war.
