It sounds like he will probably die in prison anyway. He is 69, any sentence longer than 10 years is a death sentence. Even a ten year sentence could be.
But he agrees to give the government something like 46 million in assets, to cooperate in all investigations and I believe to not accept a pardon.
What does he gain? It sounds like no matter what, he is looking at dying of old age in prison whether he cooperates or not.
Did Mueller offer to protect his family from Russian assassins?
Did Mueller threaten to investigate his wife for crimes?
Does he avoid the death penalty (with appeals, he would die of old age before his sentence was carried out anyway).
Dis Mueller agree to let him keep some assets for his family (had he not cooperated would Mueller have taken everything and left his family penniless, at least this way they still have something)?
Was Mueller discussing extradition to the Ukraine?
I’m wondering if a Ukrainian extradition was the leverage Mueller used. Ukrainian prisons are harsher than American ones and manafort would have been a target for violence in the Ukraine.
