Not entirely plausible. Hitler had vast stores of chemical weapons that he refused to use because of the mass destruction that he knew they would cause and even he didn't want that because he remembered the horror they caused after being attacked by chemical weapons when he was a soldier in the trenches in WWI. He could have utterly destroyed hundreds of thousands of invading Russian troops daily for a few day or weeks, until the Russian counter-attacked with the same weapons. But he didn't. If both sides had nuclear weapons, I'm sure the same rationalization would have taken place even if he was going to suicide the next day.
