I'm interested in WW2, albeit I wouldn't call myself a nerd.
If you want to debate, then here are some opinions on WW2 of mine:
Germany could have won WW2, but only without Hitler. Even then, if they still had to invade USSR, they'd only win in the very unlikely scenario that they'd get Western support.
Erwin Rommel is one of the most overrated Generals of all time.
Heinz Guderian is what most people make Erwin Rommel out to be.
Erich von Manstein was one of the most brilliant strategists of WW2 and one of the main reasons Germany was so successful.
US involvement in the war could only be delayed, but not prevented.
Germany could never ever have invaded mainland Britain, even with the destruction of the RAF.
Hitler was the reason for both the success of Germany and the failure of it.
Germany produced some of the best tanks of the war, but they were exactly the kind of tanks Germany did not need.
The Sherman is underrated.
While most people say Germany would have been better without Italy, I disagree. While Italy had one of the worst armies of WW2, it still did its own fair share of helping Germany. The Italian Navy kept the Royal Navy busy so Germany could focus on the ground aspect.
Many people misunderstand the involvement of Baltics within WW2. The Courland Pocket saw very fierce combat, and the Latvian Legionnaires were some of the last German units surrendered. Let that sink in - the Courland Pocket held out until the Soviets had already reached Berlin.
While Soviets had already won by then, D-Day was still an important part of the Allied efforts to end WW2.
The nuking of Japan was fully and completely justified.
Germany couldn't have gotten nukes, even if the Norwegian resistance members hadn't blown up the heavy water stations and what not.
The Soviet Union had better tactics for the use of large scale tank assaults - Deep Operations/Soviet Deep Battle.
There was no such thing as a "blitzkrieg" tactic - it was simply generals using the tanks at their disposal to their best ability.
Germany was technologically superior to the Allies, but its resources deprived them of putting them to any use.
Please don't hate me for having an opinion.
