Here's something else to consider...
Lets talk about history... Zhen he's Treasure Fleet in the 13th century was the most massive indian ocean reconaisance in history at the time, and the chinese ships were larger and more advanced than any in history up untill then, as well as having no larger predecesors untill the late 1800's; the sheer ammount of wealth it required was beyond anything ever seen before.
Christopher columbus took 3 small carracks to the carribean and becomes a more talked about figure in history than zhen he; it's outrageous!
Actually it isn't... History isn't about BIG things are, or how different they are, it's about the things in time which influenced future generations of culture, religon, politics, economies, and so forth.
Like i said... i can sympathize with people who think that the russian efforts of ww2 are being underminded, but in terms of american history, for WW2, it would make sense to learn about the part that AMERICA took in the war; for world history, it would make sense to talk about what each general region did to influence the war; and how it effected the war itself, or the future of the world.
If your arguing about the actual events that occured in history... There's really no problem with that, but anyone on this forum who's trying to advance the idea that we need to re-write history because russians weren't talk about enough... Really needs to cool they're jets.
There are much worse things a country can do to they're history, like the chinese and the germans removing distinct time periods in the 20th century.
