Trump wants to put the Army on border patrol

[Rajvik]

There are ways around Posse Comitatus, like being 5 feet on the Mexican side of the border, ...

Would that not count as an invasion of Mexico?

Teddy Roosevelt would be proud.

And won't be the last time we do so for various reasons up to and including the drug transport issue. However, I have a solution that will solve everyone's issues,  

annex everything south to either the Panama Canal or the Darian swamp and put the wall there. Everyone in central America is now a US citizen and the US has the legal ability to cut the cartels to pieces while cleaning up places like Juarez.

Note, this suggestion is semi sarcastic. It could work but no one would ever go for it because for as many people that live south of the US border that want to come to this country probably twice as many more probably don't.  BA. Probably knows about the Reconquista, I don't know how anyone who spends any amount of time in the southwest US wouldn't,  but that group specifically wants to take back the "Spanish" possessions for Mexico.
