so he hasn't really spoken about him since and that's the perfect way to handle cahavez. he has a message that's broken. his country tragically is not doing well. it has one of the highest violence rates. he's a failed leader. he'll fade away. but we still have big problems in mexico. their political system is functioning okay in some ways. they're having vigorous democratic debates and they did things with their overall approach towards the drug war that in many ways mimic what general petraeus did in iraq and afghanistan. but they haven't managed to turn the corner. and we have to be analytical in how we think about what's needed next. the mexicans will make the decision. one thing we have to think about in this country is what can we do to help the mexicans by way of reasonable gun control measures. and i'm not talking about taking guns out of the hands of law abiding americans. i'm talking about tracking the sales of semiautomatic weapons. they account for 80% of the violence in mexico. and we need to think hard about what next steps may aid modestly in their problems
