Bull. Apart from breakaway regions Georgia had a stable pro-American government. In Ukraine you don’t have any stable government but uncontrolled armed groups of whatsoever affiliation running wild with all kinds of weapons. Kiev doesn’t control a thing there as far as a dozen Russians arrives at major airbase and captures it without a shot fired. And Ukrainian naval flagship flies a Russian St.Andrew.
Not even a Ukrainian military decided which is their side, let alone Ukrainian people and you want to intervene, on part of whom?
Imagine a US warship sunk or aircraft shotdown. Whom will you blame for it? Russians, Muslims, Nazis, Anarchists, Isolationists?
Put yourself in Putin’s position.
Look what is to their South and realize how important Crimea is to Russian security.
Look at access to the Black Sea and the route of natural gas supply lines through the Ukraine and tell me Putin is doing anything we wouldn’t do.
