I don't remember if Said published any explanation for taking the stand he took at that point (maybe Doug or Jim Heartfield or someone else remembers). Though I admire Said's work in many respects (both his scholarship & activism), I think that his culturalist framework of political analysis -- Orientalism -- didn't serve him well in this case, in that it may have inclined him to believe (contrary to facts) that 'a poor nation of Muslims has been unfairly denied military aid from outside due to their (real or imagined) religion' or something like that. I recall liberal hawks played up this line: 'a fear of the specter of political Islam within Europe made the West ignore the plight of Bosnian Muslims,' laying the ground for support for increased interventions, leading to the bombings and beyond, by first of all manufacturing the non-existent guilt of 'appeasement.'
