Jabhat al-Nusra does count Syrian veterans of the Iraq war among its numbers, men who bring expertise -- especially the manufacture of improvised explosive devices (IEDs) -- to the front in Syria. Still, Jabhat al-Nusra is not the only rebel outfit to use IEDs and other groups -- some so-called moderates operating under the loose umbrella of the Free Syrian Army (FSA) have also allegedly used suicide bombers who were either willing or unwilling (i.e prisoners). Like Jabhat al-Nusra, a number of other Islamist groups also want to install an Islamic state in Syria, while even secular rebel units increasingly speak in ugly sectarian terms that demonize minorities, particularly members of Assad’s Alawite sect. Yet only Jabhat al-Nusra’s tactics were designated as “terrorist” by a U.S. administration that admits it is still trying to understand the various armed elements in the Syrian conflict, fueling all manner of theories about why Jabhat al-Nusra was slapped with the description. Also why time the announcement just as rebels as a whole seem to have gained a renewed momentum? The key, it seems, is the alleged links to al-Qaeda in Iraq.
