if trump is believes that going hard after the cartels is a + thing,then fuck Mexico and it's constitution,which is pretty much butt wipe anyway. Mexico declare war? fuck them then.
i do believe that there might be a less incendiary way to deal with them. 1st absolute control of the southern border with barbed wire,watch towers,free fire zones,active and passive surveillance. nothing lives that tries to cross it without through inspection. yes,inspector corruption would be an issue. it is now. there was a Napolitano vid with Col. Macgregor advocating using a full reg mil commitment to protect the border. we did against Pancho Villa and doing it again makes perfect sense. better than protecting Europe from the "evil Putin".
2nd expelling them from the large areas in this country that they occupy. again likely need reg mil action. cops and NG unlikely to be able to deal. no Posse Comitatus is a non issue for several reasons. the wording of the law itself for 1.they are already hostile invaders.
