Just look what 9th and 10th graders are being taught in the Islamic kingdom of Saudi Arabia.
The books were published and handed out to 9th and 10th-graders despite Saudi Arabia's promises to clean up textbooks in the kingdom.
Ali Al-Ahmed, director of the Institute for Gulf Affairs, told Fox News: 'This is where terrorism starts, in the education system.
'They show students how to cut (the) hand and the feet of a thief,' he said.
The textbooks were printed for the 2010-2011 academic year and translated from Arabic by the institute.
In one, for ninth-graders, students are taught the annihilation of the Jewish people is imperative.
One text reads in part: 'The hour (of judgment) will not come until the Muslims fight the Jews and kill them. There is a Jew behind me come and kill him.'
According to the translations, women are described as weak and irresponsible.
Mr Al-Ahmed said the textbooks also call for homosexuals to be put to death 'because they pose a danger at society, as the Saudi school books teaches'.
Mr Al-Ahmed said: 'If you teach six million children in these important years of their lives, if you install that in their brain, no wonder we have so many Saudi suicide bombers.'
