Saber Rattling - Doubling Down

Mexico's response to invasion would be swift and brutal.
Have you ever seen Red Dawn? Glotones/Patriots age 12-72 would take to the hills and quash any attempt at invasion with slingshots, can openers converted into into ball crushers,IEDs made from Duracel batteries. Flamethrowers would be fashioned from bic lighters, crossbows from blow driers. It would be over in a few weeks, amigos.
