They are treading a tightrope here. They hate the West worse and worse, but the cumulative list of things they can get away with without a pushback seems to be slowly shrinking. The Wrath of the Awakened Saxon and that sort of thing.
Well I am (gratefully) surprised that we haven’t seen more attacks. Let’s hope you are right about the West’s growing resolve - though it still has not been really tested. Europe, I fear, is all but lost, save the Central Powers, which are showing backbone against the Muslim hordes.
