It’s interesting to see how different countries’ textbooks differ about the same issues in US history. I think it would be even more interesting to branch out more into world history (maybe it would be too hard to find US textbooks that deal with non-US-related events…).

For example, in the US we learn that the Spanish American War started because the Spanish blew up the US warship Maine while it was in Cuba. However, the Spanish textbook claims that the Cubans blew it up to bring the US on their side against Spain, the Cuban textbook claims that US agents blew it up themselves to make an excuse for declaring war, etc. And of course the Philippines has a completely different opinion about the whole thing.
