I think it is interesting that they appear to be going more for drug processing centres. I would hope that they are trying to break the local insurgent/narcotics nexus. I do not know all that much about the poppy/heroin cultivation process and timelines, but it would be interesting to map the timeline of the strikes against the poppy planting/cultivating/ harvesting/processing timeline and guage the impact on cash flow in the area.
Men fight for many things, but in a poor area with limited means money always figures pretty highly!
