That 750 billion is conventional weapons,which I have said multiple times The US would kick the shit out of Russia with.When it comes to the most powerful weapons they are even, and Russia will go scorched earth before losing to The US.
Again, you say Russia will start an all out nuclear war. I disagree. Name a country where Putin has dropped a nuke? How many nukes has Putin lobbed into the sea because he was mad, like NK; since you say he's a madman. You've been bullshitted my friend.
Everyone knows what all nuclear nations have. The point is Putin hasn't exhibited any abnormal nuclear actions ... like NK has. Yet, you're so scared. So the question becomes why are you so scared of Putin initiating nuclear annihilation, when he's made no actions consistent with that purpose; especially in light of the fact that another nation has paved the way (NK). Again, do we just obey all of Putin's commands, because we are a scared #1 superpower; or do we just say Fuck Russia! I say Fuck Russia; but I respect the rights of others to be scared of an unsubstantiated, unlikely threat, and live in obedience to the thug doing the threatening ... for life.

There is no nuclear war. There is no evidence that Putin will initiate an all out nuclear war. Your fear is manufactured in your mind with the help of Putin's manipulations.
