I really don't think these sanctions will do much good on either side. Sanctions against Russia won't work because Putin already has a lot of support over there and all he has to say is "The West is to blame for our unfortunate situation". He could then convince Russians that he's the only one who can stop the West from getting their way, making him even more powerful than before. This is how Fidel Castro had been able to maintain how power in Cuba for so long before his retirement. Russian sanctions towards the west (or at least the USA) won't work because it'll only effect a small number of Americans. Most people won't feel the effect of this.
This won't solve anything. We'll either have a pro-Western patsy in Ukraine or a Russian patsy since nobody apparently believes in self determination amongst nations anymore. I would say the U.N. should declare all nations to stay out of Ukraine's affairs save for trading and have security guards around the boarders of the country, but unfortunately, the U.N. is pathetic because it is ruled by the security council which happens to have, the US, Britain, France, Russia, and China as permanent members with veto powers, meaning that a vote for such a measure would never take place.
So for right now, we'll have to hope for the best, most peaceful outcome.
