Hate to kill the joke, but you can't get the peace prize posthumously.Since the standard for getting the peace prize are apparently pretty easy now I'd say he could get the peace prize posthumously for accidentally falling and killing himself.
Barak Obama goes to Moscow to negotiate over the Crimea. He tells vladimir that world peace is important. He is after all a Nobel Laureate in that regard. He then shows his Nobel Peace Prize to Putin. Vladimir smiles puts on the medal and never gives it back
LOL, hilarious.
Since the OP never said it had to be the Peace Prize, he might not be able to do it in the sciences but what about literature? While I think of Winston Churchill as much more able to use the language efficiently than Putin, how about this.
Putin likes to wrestle bears (if memory serves and the legends are true) and do other things to show his power. He decides to use this to his advantage and promote himself as one of the world's greatest ever leaders because he can wrestle bears and such. He creates a work analyzing many of the great world figures and personality traits that have mirroed their legacies. He can trash a couple of Russia's great enemies mercilessly (Hitler for many things, Napoleon for his height - even though his shortness was exaggerated - and probably other thigns, too). He can praise a former Nobel laureate (Churchill) which may get some attention. He can extoll the virtues of the leaders he thinks the committee would like to hear about.
In the end, someone else has to really help make it a polished work, but he would have magnified himself but at the sme time added to the world of lterature something that can at least be of interest. He might have to bribe some committee members, but it *could* happen if he chose to pump himself up in this manner.

You forget, Russia DID work out a deal to get Syria to dispose of its chemical weapons.Make him somehow negotiate an armistice in the Syrian Civil War.
How about Putin ramps up the pressure even more along the Russian border by demanding the return of all Russian speaking areas. The West have kittens but can't just give in, so in return for the land (it's other peoples anyway!) the west get Putin to agree a deal reducing the worlds nuclear arsenal. The West sells the deal to their people as: Averting WW3 and making the world a safer place! Nobel prizes all round.
