sd_matt: Legalize which drugs? I ask because I’m all for legalization of marijuana, but not for legalization of cocaine or heroin. I agree that legalization would minimize some of the threat, but Mexico has a host of other ills as well.
In terms of invasion, Mexico is a huge country and the terrain favors the insurgent element over the invader (you’ll remember the issues Gen. Pershing faced during his Punitive Expedition against Pancho Villa).
I don’t think there’s an easy answer, but the situation is clearly deteriorating.
