here is what happened to hitler
the bastard took lots of meds for the last few years of his life, once the war turned agaianst him, actually (i.e. while stalingrad proceeded, and italy got owned)
he spent the last month or so of the war in a bunker in berlin, commited suicide after marrying eva braun (foolish woman)
edit: if he survived, which i seriously doubt (he problably had parkinsons disease) the mossad WOULD have found him
