no. us secures border. period. what happens in mexico is mecicans' problem. they will continue to get what the accept in terms of cartel actions and government responses. the only stable solution to elimination of the cartels in those countries is for their people to start murdering cartel members in the streets. as long as the people prioritize short term individual safety over long term collective safety, they will have to live with tyranny. no external force can get this ball rolling. we can help by securing our own border to limit cartel funds, and by funding and arming any resistance that occurs. we might even be able to infiltrate to organize and train them. simple invasion will end like afghanistan did though -- the emasculated population will remain emasculated, and the power vacuum will be filled the moment we pull out.
