"There were entire classes of weaponry only possessed by the Germans, such as guided missiles, rocket powered flight and of course jet (until very late in the war), helicopters, cruise missiles, anti shipping missiles.."
Bzzzzt. Wrongo! You really should go bone up on who had what more. The US had all of that too (USN mainly) and so did the Brits. As Ack Ack noted
the German was success from tactics, not technology. Also, as was noted, the Allies had the trump card - das nOOk. Something old Adolph never
had (nor came close to) . Nor did the Germans have a decent navy with aircraft carriers. Something the US had an abundance of. Hell even the British
had those! You're vision is just warped from those leather undie colored glasses. <heel click, arm thrust> "Seik Hellp!"
p.s. the Germans had NO chance in winning the war because they did not have the technologically advanced industrial might of the United States. That
is the reason the Axis lost in a nutshell. The US could out research, out develop, out produce and out "reach out & touch somebody" a magnitude more
than the Germans could - even adding in the rest of the Axis. The US could project an enormous power across both the Atlantic AND the Pacific oceans
AND maintain and supply them to boot The Germans could not. (example: their Afrika forces just south of them).
