One of the ways in which the Anglosphere can oppose the efforts of Al Qaeda (which I will use as a standing for insurgent Caliphascism in general) is to punish the states that support Al Qaeda activities. This wil certainly have a large negative impact on Al Qaeda but it’s unlikely to eliminate their activities completely as some might hope. This is another facet of the no step functions point. Al Qaeda can go underground (like the Red Brigade) or base themselves in lawless regions of the planet. However, their capabilities will be greatly reduced in this situation short term and long term, as more states become self ordered ones Al Qaeda will find fewer recruits and less support. There will no climatic battle, but slow and unsteady progress which will gradually reduce the threat from Al Qaeda until it’s no longer significant.
