Well, David I would disagree. I could post up whole books worth of historical fact much already hashed beyond recognition. But, it is when someone comes up with a plausable... and I do mean plausable (none of this Me 262 in 1940 stuff) alternative for World War 2 that I actually do put up some of the best researched fact and analysis on this, and other, board(s).
Limiting a board to just dry factual constructs would remove much of the flavor, discussion, and learning that actually takes place here. It would be a very boring world without "What-ifs."
