Whether Crimea is Ukrainian or Russian doesn't matter one bit to me, so it's hard for me to get outraged over Obama not sending arms or troops to help return Crimea to Ukraine.
What does bother me is the fact that Hillary wanted US arms and troops to back the overthrow of another secular dictator on behalf of Islamist rebels, because obviously doing so worked out so well for Libya and Iraq.
Do you have any evidence that Breedlove was not independent and acting for Hillary?
That would be a bit strange as sending arms to Ukraine is a Republican position with 60% of the Republicans and only 39% of the Democrats supporting it.
