As we all know Reinhard Heydrich, the architect of the Holocaust, was assassinated in 1942 in Prague. He very easily could have survived given the circumstances, so let's say the attempt was botched, he lives and survives to the end of the war. What then for him? He would be one of the very top Nazis wanted by the Allies for war crimes, would he just commit suicide or try and fleet the country? Could he flee the country and if so could he really survive on the run? He'd be wanted a lot of people, so living out in the open wouldn't be possible in places like Argentina or Spain. He'd have to pull a Mengele and live under an assumed identity. But with having survived Israel would want to grab him badly, much more so than even Eichmann, and would probably want him alive rather than assassinated due to the huge publicity capturing someone beyond even Eichmann's position in organizing the Holocaust. In fact he'd probably be second to only Hitler on their wanted list. Would he even have a chance to survive on the run then, especially once Israel gets involved in Nazi hunting?
