South America may become a battlefield.
This guy breaks it down well.
It could get real ugly.
They only way in my opinion that Trump will get his wall is if plays a "love thy neighbor" angle instead of the "blocks terrorists, illegals, drugs, human trafficking, etc…)
He needs to tell the opposition that we need a wall with specific entry/exit points in order to identify each person who crosses. That identification process would be recorded, and it would ensure that whoever crosses is accounted for. So if a Mexican enters into the U.S.A., either temporarily or permanently, and if that Mexican is killed or dies on our land, we need to be able to respectfully send the corpse back to it's family or friends. Or if an American crosses into Mexico and is killed or dies, we need to be able to get the corpse back here to the family of the deceased. It goes both ways. We need to love our neighbors. We don't want the Mexicans to be keeping dead American bodies, and we don't want to keep dead Mexicans here. We have to return them respectfully insted of disposing them without notifying next of kin.
