Yeah, he is not getting back into anything. For the remainder of his life the most sure way the world over to get an arms deal busted will be directly, indirectly, tangentelly, or in any way otherwise involving Viktor Bout.
There are going to be files kept on what he eats, how many steps he takes an hour, and how many times he sneezes.
Besides, his contacts are outdated and/or burned by now, and he has been released, not pardoned. He sets foot outside of Russia and he will find many nations with waiting jail cells.
