Thermopylea is a good example of that.

So what if the Germans built an aircraft carrier or some fance new planes. The sheer air and naval power that America commanded at the time meant sticking a couple of fleets in Europe would decimate the Kriegsmarine.

Sure, the Stürmgewehr was an incredibly well designed gun, but again, the Soviets were just able to make so much more weapons and ammunitions for a fraction of the price. A short burst of machinegun fire from German guns equates in cost to a rocket barrage from the Soviets (OK, I’m exaggerating, but the cost difference is still massive)

Let’s also not forget that close to the end of WW2, the Werhmacht numbered little more than 400,000. The Soviets had over 1 million, America could potentially match Germany’s forces, and then then there’s all that resistance to deal with from occupied territory, especially the well-organised and lethal French Resistance which alone can also match the Wehrmacht in sheer numbers. You also have to take into account that Germany will eventually ***** off Switzerlanland (a nation where military training and service is compulsory and repeaed) which can chuck another million soldiers into the fray without breaking a sweat. Of course there’s also the Allied powers across the globe, from Africa to Australia to the Middle East…

I simply don’t see how Germany, with no matter what fancy weapons they have (except perhaps the atomic bomb), can withstand the sheer military size of half the world combined.

Utter nonsense; P-51′s and the DeHavilland Mosquito did shoot down ME-262′s that were caught unawares cruising, on take-off or out-turned but not because they could match the ME262 s top speed of 569 mph.

No reciprocating engine could match this jet.

Also the Graf Zeppelin would not have been very effective as carriers were almost never used in the European theater as

1 carrier based planes are inferior to land based planes
2 there was no need for them as all targets could basically be reached by land based fighters.

Also this carrier would have been not very useful as the German navy was so out numbered they had no hope of engaging and defeating the UK's navy nor the US's.They would have been better off putting the resources to use else where the only useful ships to the Germans were subs.

Other than these problems good list although I disagree about the viability of the V2 as a weapon for anti military role as it was not cost effective as a actual weapon but as a terror weapon. Hitting military targets would have lessened the terror.
