Of course a war isn't as simple as killing the enemy. I assumed that was a given.

I feel sympathy for the people who are forced to join violent gangs. I also feel sympathy for the young, uneducated, impoverished people who join such gangs because they feel they have no other option. But if they are committing violent acts not just against rivals but also against young, uneducated, impoverished people who are completely innocent, then the amount of sympathy starts to fade. When and if the Mexican government decides that they have truly had enough, these misguided youths still have the option of throwing down their weapons.
