So wait. According to some comments here, Putin is basically a evil mastermind who is going to be stupid enough to kill off the Polish President by having the guy's plane crash in Russia itself?
I know the guy is a perfect fit for a Bond villain, but he's not stupid.
One cannot always get one's victim to be in the right place at the right time, I expect.
One must seize the opportunity where one finds it.
But hey, who knows?
It might simply be a plane crash, too.
