If Hitler had been captured he'd almost certainly have been captured by the Soviets and the chances he'd make it to Nuremberg are quite slim. He may have been publicly executed or just disappeared. Considering how many soviet lives were lost in WW2 it'd be unsurprising if the officer in charge of his capture didn't just take matters into their own hands over a personal grudge.
It's not though. The question makes the assumption that he would have been handed over for the Nuremberg trials.
But the Soviets were fucking ruthless against Nazi Germany. They were REALLY driven by hatred for them. If a Nazi soldier surrendered to Russians, a summary bullet to the head was often the more merciful outcome.
And it was the Russians that would have found Hitler first, so it's far more likely that they would:
execute him on-the-spot
torture him until death
have their own trial for him in Russia before torture/execution.
It's not though. The question makes the assumption that he would have been handed over for the Nuremberg trials.
It absolutely misses the point, and so have you. It is a hypothetical whereby he was captured, turned over to the Nuremberg trials, and found guilty. That's the basis of the hypothetical. Saying that wouldn't have happened absolutely misses the point of the hypothetical.
