Awesome list! I can't think of a lot to add, but there are definitely a lot there that I wouldn't have thought of.
Let's see... most of what I can think of is more pre- and post- WWII, but they follow the "thread" of Nazism.
A:
Allen Dulles - CIA head who created the MKUltra program.
(Secret) Antarctic Base - where the inner cabal of Nazis escaped to after Allied victory.
Ariosophy - the version of Blavatsky's "Theosophy" that the Germanenorden and Thule Society held to.
E:
Esoteric Hitlerism - the post-WWII descendant of ariosophy, widely held among modern skinheads.
O:
ODESSA - Organisation der ehemaligen SS-Angehörigen (“Organization of Former SS Members”), a secret network by which Nazi brass escaped prosecution, allegedly with the help of the Vatican (the Knights of Malta / Hospitallers, specifically).
Order of the Solar Temple - Post-Crowley OTO offshoot lodge, alleged to have been founded by an ex-SS officer, which ended in mass murder/suicide.
P:
Project Monarch - Supposed mind control program that developed from the CIA's
MKULTRA project, both of which were supposedly developed under the influences of....
Project Paperclip - the OSS (proto-CIA)'s program of recruiting Nazi scientists.
Protocols of the Elders of Zion - Russian antisemitic tract alleging a global Jewish conspiracy, used in various Nazi propaganda efforts.
S:
Skull & Bones society, widely held by modern conspiracy theorists to be a continuation of the Thule Society, and hence, the Illuminati.
U:
UFOs, Nazi - I know you already had this one (V-7); here's a detailed site about it.
V:
V-2 Rockets - Nazi ballistic missiles.
Vehm, Holy - Medieval German secret courts.
EDIT: ...and it goes without saying that Godwin's law is totally out the window in this one.... :)
