Anybody watch the History Channel program about German secret aircraft?

I thought it was complete BS, they said that if the Germans could hold the line until 1946 then the flying wing bomber could drop a nuke on NY and Germany could win the war.

I think this is a somewhat simplistic view of the war.
Let's assume that the Germans delay the war for exactly one year, that means by Spring of 1946 the Soviets are at the Oder River and the Western Allies have just crossed the Rhine.
Now word gets to allied lines that the Nazi bastards just nuked New York City, are the allies going to pack up and go home? No! They are going to finish their push into Germany and probably kill most of the population as revenge.

Remember that with Hiroshima and Nagasaki it was the US that had Japan by the throat. If Germany nuked an allied city when the allies had Germany by the throat, all it would do is piss us off and most likely lead to a lot of German civillians getting killed.
