Not really. At the time negotiations were already quite problematic. And if anything it had the opposite effect. The extreme right became discredited for a few years. They only made a gradual move back into something resembling respectability when negotiations didn't achieve peace for another decade or so.

It occurs to me this time around that there's an interesting relationship here - 9/26 is forgotten, while 9/11 is remembered. Do something charitable, and not patriotic, sometime today.
