Anders Behring Breivik said he was a boy when his life's path began to turn. It was during the first Gulf War, when a Muslim friend cheered at reports of missile attacks against American forces.
"I was completely ignorant at the time and apolitical but his total lack of respect for my culture (and Western culture in general) actually sparked my interest and passion for it," the suspect in Norway's bombing and mass shooting wrote in his 1,500-page manifesto.
The 32-year-old Norwegian said it was the NATO bombing of Serbia in 1999 that "tipped the scales" for him because he sympathized with Serbia's crackdown on ethnic Albanian Muslims in Kosovo. A year later he said he realized that what he called the "Islamization of Europe" couldn't be stopped by peaceful means.
Police and Breivik's lawyer says he confessed to, but denied criminal responsibility for, Friday's bombing at government headquarters in Oslo and the mass shooting later that day at an island summer camp organized by the youth wing of the ruling Labor Party. At least 93 people were killed in the attacks.
Breivik's manifesto chronicled events that deepened his contempt for Muslims and "Marxists" he blamed for making Europe multicultural. He suggested his friends didn't even know what he was up to, and comments from several people who had contact with the quiet blond man indicate he was right.
