War Gaming vs History
As a war gamer, you look at who lost a war and wonder how they could have won as a technical problem, regardless of how repellent their ideologies are. Same for a lot of folks who play Axis & Allies to see if there's a way for Japan or Germany to do better than they did in WWII. Short answer, if they weren't lost in nutty fantasies of cultural superiority, they might have done better by not fighting the bloody war at all. Taking a good look at the odds requires sanity which checked out long before any DoW in the German and Japanese's leadership's cases. Denying reality bones you in ANY endeavor. Any questions?
Here in the US, we have folks who dress up and fight as Confederates in Civil War reenactments. I'm a Texan with ancestors that were Confederate war heroes, but I look at them as a mixture of good, bad, and ordinary people fighting for a shitty cause.
Freedom for states to continue an oligarchy dependent on slave labor? 
. 

Sorry. That needed to be removed with all due force and am damned glad it's in the dustbin of history. Sure, once we did that, was everything milk and honey? No.
I can't look at a Dixie flag without feeling a deep sense of shame and outrage for all the wasted lives before, during and after the American Civil War because of the benighted stubbornness, hatred, and violence growing from that poisoned tree of bigotry in Southern culture.
Our history is painful, but it informs and challenges us to be better.
This site tries to accomplish a little of both, wargaming better outcomes for those that lost (as well as less Pyrrhic victory scenarios for that won) and sorta playing with history both to inform us about the details and turning points and personalities involved, debate their importance, and maybe tell a good story along the way.
Holocaust deniers and apologists need not apply. Those facts you can't argue away. Apologists may point to the horrors perpetrated by various Communist regimes as a reason that Germany did it, but that's bollocks.
Germany chose to do evil deliberately not to respond to a threat of Communist takeover per se but to fulfill their ideological agenda.
The Soviets and others did it to enact and protect their socialist utopia, using the most ruthless and cruel methods imaginable.
Both are inexcusable bastards of the first water. History is clear on this.
