Hell no. They can keep that mess down their where it belongs. We don't need Mexico as a dependent. However, we will probably end up with troops down their these guys have tonnes of money to fund their little war and I don't see it stopping anytime soon. Plus, it will give the Government more power to enforce its Drug Laws on us to an even greater extent. Just think if these Mexican drug gangs start doing hits in the US on a large scale. The Government will declare them "Terrorists" and buying Drugs will put you in Homeland Security type situation for supporting terrorists.
I can see it now.
