A few thousand? Soldier estimats range between 31,000 to 40,000. ISIS contorlled poplutaion ranges to 6 million. And thats just ISIS. That doesnt take into account Al-Qaeda, Abu Sayyaf, Ansar al-Islam, Armed Islamic Group of Algeria, Army of Islam, Boko Haram, Taliban, Egyptian Islamic Jihad, Lashkar-e-Taiba, Jaish-e-Mohammed, Jemaah Islamiyah, Harkat-ul-Jihad al-Islami, Harkat-ul-Mujahideen, Indian Mujahideen, Tehrik-i-Taliban Pakistan among many others. Nor does it take into account the number of fundamentalist Islamists. You know...the 'peaceful' Islamists that kill their own children for daring to date outside of their religion or for getting raped.
