Interesting thought, except for one small thing. We have already been told by the current generation that everything we learned was junk and that our nation IS responsible for ALL the world's ills including but not limited to:
Slavery
Concentration Camps
Ethnic Cleansing
Piracy (possibly true)
World Domination
Child Labour
etc etc
In short my generation has been made to feel guilty for just about every ill visited on mankind for the past 5-600 years ad infinitum ad nauseum and thanks to the Internet and the more scurrilous left wing rags, 'modifications' to our perceived history continue exponentially until, wracked by guilt, I want to chuck myself in front of the nearest bus.
You all do it too. Maybe not intentionally, but you continually rubbish our history and tell us what wankers we were. (Maybe not you personally Bob - but you get my drift)
The worst 'crime' of all being the familiar old statement that we 'would now be speaking German etc' without so much as an acknowledgement that without the sacrifices made, the USA would also be speaking with a guttural delivery.
So, personally, I don't have to imagine that everything I learned was wrong (such as the UK was generally a force for good in the world) - I get told it every day, and the subliminal collective guilt has neutered us as a nation.
If I picked up a history book from the 50's, almost everything in it would be 'wrong' by today's standards, with the exception of that history which is never disputed, and for that, you'll have to back almost 1,000 years.
