Both countries have enough nuclear weapons by themselves to likely blow up the world X amount times over. I don't see the point in acting like we are getting rid of all our nuclear weapons when we aren't.
Besides, it's most likely already that Russia has more nukes then the United States. Furthermore, Russia will never blow us off the map for two solid reasons.
1.) Their economy is still highly reliant on ours, to blow us into pieces would send their economy and the world economy into shambles.
Which leads me to #2:
2.) Do you really think the international community would sit by if Russia were to take out the United States? Too many countries are invested in the United States to see their investments to go bye-bye in a mushroom cloud (Saudi Arabia, China, Europe are just a few examples).
Are you being serious in this post or is it meant to be a joke?
