The Third Reich never ended.

-nazis had many technical divisions, one of them was called the SS E-IV, this was headed by Hans Kammler with input from the vril and thule societies
-nazis developed a radical new method of propulsion through colliding electromagnetic and electric fields with their breakthroughs in quantum mechanics
-disk shape and cigar shaped aircraft began to be developed in the early 40s
-due to small numbers produced (less than 10 overall) they were only once or twice used in combat (allies called them foo fighters)
-1939 the nazis had a civillian expedition to antarctica
-1940-1945 the nazis had military expeditions to antarctica via u-boats loaded with construction supplies and personnel to build a nue-berlin under antarctica
-the u-boats would dive 200m under the ice shelf of nueschwabenland and follow the warm water lake run-offs that lead to the mainland of antarctica
-they constructed a massive base and sucked millions of reichmarks of funding that could have been used for the eastern front (1 XII u-boat could have bought 500 tiger 2s)
-after the war 30 XII u-boats missing, saucer sightings in rural areas over austria and german (SS EIV unit possibly collecting their loved ones for the journey to the antarctica base)
-1947 america sends 1/3rd of the navy to antarctica, loses a ship and 2 planes to "disk aircraft that ascend from the ocean"
-1952, washington dc airspace is invaded by a nazi ufos that fly in the trademark luftwaffe bomber "V" formation, point of this exercise of power most likely a warning to america not to militarize antarctica
-1960, antarctica treaty and plantetary body treaties signed, this means no country can militarize or settle antarctica or any planetary body (ie the moon)
-1965, us launches nuclear icbm "test", it is shortly after shot down by a nazi ufo
-1968, above ground nuclear weapons tests are banned under the nuclear non proliferation treaty
-1991, international space station captures footage of a ufo hovering in orbit (this is very common occurance) and then a bright flash coming from earth, and a missile travelling very fast heads to the direction of the ufo, the ufo takes a 90 degree turn and accelerates by scientific gauging to around 100,000km/hr within 3 seconds

taking from this we can conclude that:
-nazis are far superior to the world's militaries
-they have impentrable base under neuschwabeland portion of antarctica
-possibly a base under the dark side of the moon
-destroy nukes and possibly meteors (going by the russian meteor where a ufo rams straight through it and out the otherside)
