Ayman al-Zawahiri's recently assassinated envoy
- Abu Musab al-Suri - may well have considered ISIS actions in Northern and Eastern Syria to be counter productive and over the top. The killings beatings and beheadings of those it considers its enemies - most everybody - did little to enhance the image of Salafist Jihadism, or win the hearts of ordinary Syrians. However it would be wrong to characterize al-Suri as a moderate in any way shape or form. His January 2005 statement below, which was released to several websites at the time, illustrates his uncompromising approach to the killing of civilians - especially those who voted for George W Bush.
'I feel sorry because there were no weapons of mass
destruction in the planes that attacked New York and Washington on 9/ 11. We
might have been relieved of the biggest number possible of voters who elected
Bush for a second term! The last option remains the destruction of America by
strategic operations through nuclear, chemical, and germ weapons of mass
destruction, if the mujahideen were able to get them, in cooperation with those
who possess them, or through purchasing them, or through manufacturing and
using primitive atomic bombs, called dirty bombs' [radiological weapons].
