Miko, I'll offer you a good bargain for 3 150Kt warheads, only $200,000 each. I can also give you a small nuclear reactor as a bonus if you'll buy all three.
Warheads are in vegetable stock facility in Moscow, customs is your problem. The reactor is right outide my window, Moscow, Kosygin str. 2, you'll have to disassemble and pack it yourself, and I suppose you'll not take the water from the refrigirating pond.
How fast can you deliver cash to Moscow?
