That is a fair observation. There is no simple solution to any of this, but the answer will not come from something military that is led by the west. It will come from something political that is led by people within the region.
There is a huge amount that we can do, but it should mostly involve encouraging and enabling other people. It should not be a rerun of Iraq in 1991, when, although there was a grand coalition of Arab states, it was still led by the United States, or of 2003. If we are to win, the lead should come from within the region and should include a long-term political vision. Otherwise, step by small step, we will enter a much darker age of war and radicalisation.
