John, Steve or anybody else with a background on SL

I'm working on a short paper discussing the decline of SL. Basically I'm arguing that

1. The removal of Guzman was critical in the defeat of SL

2. This was only possible because SL was a highly organized "spider organization"

3. This is not common among most insurgencies because they operate under a "starfish" structure in which is not easily decapitated. Therefore a comprehensive strategy to secure the population is preferred to enemy focused targeting.

My question is...do you think removing Guzman was the silver bullet that caused the decline of Sendero or do you think the Rondas Campesinas and other initiatives by GOP were the real reason for their success.
