The Taliban are not Arabs. The Chechens are not Arabs. Neither are Jamaat al Fuqra, Jamaat al Tabligh, Jemaat i Islamyia or Abu Sayyef. Hezbollah is funded by the Iranians.
Their targets and victims include France, Italy, Germany, Russia, India, Australia, the Philippines, as well as America and Israel.
Certainly there are Arabs involved, but the foes we fight are not united by Arabic.
