See part of the problem as I see it is that people who advocate this very hardline towards Russia with regards to Ukraine live in this fantasy world where they think that the US can solve all the worlds problems. It is rather amazing how right wing militarist neoconservative fantasies blend well with liberal fantasies in this regard. This is one reason why people like Ariel Cohen and Victoria Nuland get along well with people like Hillary Clinton and Barack Obama with regards to this issue. They all have this common fantasy that the US can solve all the world's problems. It is a fantasy only. It is not reality.
