If you think Obama is going fire nukes on Russia for any reason, you clearly do not understand our predicament. And the Ukraine gave all its nukes up. Russia has more to fear from Israeli nukes then it does from American nukes. That is how bad our predicament is right now.
Sorry, but you are nuts, we are not on the verge of WWIII, Putin is not as insane as you are, and is not wanting for Russia to disappear in nuclear dust.
Russia is weak and and is just trying to get away with what it can, until someone slaps his hand.
This is your own nutty obsession, in your own head.
