A couple of asides are that it's very interesting to do the same sort of thing with "Russia" in more contemporary times. Our minds do very strange things when reconstructing the past. At the eve of the Iraq war, 72% [2] of Americans supported war. Now nearly half [3] of Americans claim they opposed the war. And the interesting thing is that people probably do genuinely believe this. Our brains do an absolutely phenomenal job of letting us lie to ourselves. Probably the one thing that inhibits progress more than any other!
