And I'd prefer to believe the history books from an unbiased country rather than these from a biased one.
Anna,
There is no such thing.
The history books produced by people who live in your country are written by people with a bias. Just as the ones written by Americans are written by people with a bias, and the ones written by Japanese, French, Iraqis, Germans, or any other nationality all have a bias. There is no such thing as an unbiased source.
The question to ask is, which country has the most consistent history of allowing its citizens to freely investigate the past and to speak their opinions without fear of government reprisal. Your country does not have a good track record in that area, so your textbooks are more likely to be not just biased, but
wrong when compared to textbooks that come from some other countries.
America has done some stupid things over the years, but our academicians are rarely afraid of the government punishing them for writing or speaking about what they have discovered. So the people who write our history books might have their own biases, and often disagree with each other -- but at least the government does not use the textbooks for its own propaganda.
When looking for a history book, you should look for ones that come from countries where scholars are not afraid to disagree with the government.
