Putin is seeing his world fall apart because he has no power without high oil prices.
So it is completely in his interest to have oil selling for 3 times what it is selling for today.
As an ex KGB operative, the solution is simple - hobble Saudi Arabia's ability to produce oil with 10 well placed, suit case sized nuclear bombs.
Has to be an almost irresistible temptation because he can place the blame on Iranians or ISIS.
Since only 1% of the Saudi's benefit from the wealth of this country, the overall damage will not be that great.
My prediction - oil at $135 by year end. This has to happen.
