Really? What's the point of this stupid question?
I want to humor OP's question because I think OP doesn't know who Putin is. It may look like Putin is using everything at his disposal but you will never mess with an old man who works at a job were men die young. Vladimir Putin is a spy for USSR before becoming the President of Russia, and before that he is also the head of FSB(Sort of KGB) at the time of Boris Yeltsin. If you do not get the gist of what I just explained OP, then to make it clear, I am rooting for Putin in this hypothetical fight.
Well if they got problems with each other let them fight
Putin use to fight with bears so ....
Let them both show who is the real men russian style
Drink vodka and fight
