Terrorism has a homegrown dimension. Many of the terrorist plots uncovered since 9/11 have involved U.S.-born or naturalized U.S. citizens.
For example: A white American convert to Islam is suspected of plotting to attack U.S. military personnel in Virginia. A group of Somali-Americans from Minnesota were intercepted as they tried to join a radical Islamist group in Somalia. A Chicago man is accused of plotting the terrorist attack in Mumbai. Five Virginia men were taken into custody after they sought to contact al-Qaeda groups in Pakistan. An American-born, Palestinian-American army major is charged with the mass shooting at Fort Hood and is suspected of being radicalized at U.S. mosques.
Violent jihadist ideas not only circulate in this country, but occasionally take hold in the minds of Americans.
