Many factors. First of all, Ukraine applied to NATO in 2008 which is basically anti-Russia alliance. Mind you that back in the 80's Russia had half of Berlin and in XXI there are tens of thousands of US troops in Central - Eastern Europe (Poland, Baltic Countries, Romania etc). Now NATO wants to get Ukraine and Belarus too and anybody expected Russia to sit back?
Secondly, gas pipes are going through Ukraine and Russia is dependent on the sale of its natural resources. If US controls Ukraine they can easily block it.

1. NATO does not accept coutries that don't control all of their territories which was the case with Ukraine.
2. Most of the Russian gas went through Nordstream (NOT Ukraine) and if US can control foreign countries so easily why they couldn't stop Germany and co. from buying it in the first place, would be much easier.
