Does ODESSA really exist?

This is got to be one of the scariest conspiracy organization theories next to the Kennedy assassination.

If ODESSA really exists, it ranks as one of the most successful underground secret organizations that has never been compromised. It makes you wonder how the Nazis lost the war with such a ruthlessly efficient organization.

Right now the HISTORY CHANNEL is showing a MysteryQuest special, "Search For Odessa". It's more than interesting to watch; it's downright creepy. Ostensibly the theory is that ODESSA was able to manipulate the governments and officials of former Allied countries and Axis powers to ensure hundreds of SS and Nazi war criminals escaped mostly to South America. Most disturbing is the alleged connection to Roman Catholic priests and by implication high Church officials in Rome, helping German war criminals procure false identity documents in order to escape Europe. What kind of blackmail did ODESSA have on the Roman Catholic Church in Vatican? Was that fiction book I came across two decades ago closer to the truth than I think? The Nazis had something dark and terrible to use as leverage against the Vatican. Conspiracy theory: The Nazis had located the tomb of Jesus and his bones inside. The revelation of Jesus' earthly remains would collapse Christianity as we know it. It would have proven that Arian Catholicism, not Roman Catholicism should have been the Church in Vatican today. Who knows? This is more than a couple of German SS and Nazi thugs holding pistols to the heads of a couple of Catholic priests and forcing them to forge identity documents. More, how did ODESSA slip through the nets of the vengeful victorious Allies, especially the enraged Russians? The conspiracy theory is that ODESSA had the money and influence to use it all: bribery, blackmail, sex, technical information, you name it, to use upon the Allied military and government officials to procure safe passage out of Europe. ODESSA is thought to have played the Americans and British successfully against the Russians and vice-versa, offering invaluable technical and espionage information of all the Allies to each other in exchange for safe passage. Even Josef Stalin may have been sucseptible to secret bribery if the dictator was offered a treasure trove of technical and espionage information that would have given him an immense advantage over the Americans and British in case of a World War III in 1947. And in the end, ODESSA is thought to have easily resorted to murder if necessary. Troublesome people just disappeared or were found dead.
There's compelling evidence, mostly accepted today, that the worst of the worst, Adolf Eichman, Joseph Mengele, and Boorman all ended up safely in South America. These guys are all dead, but they escaped international justice and that's the troubling outcome. This may go over the heads of anyone under the age of 30 today, but that dark period in earth's history is but 64 years ago.
