NOT as favorable to USA; we'd lose many allies worldwide, even Canada might not want to deal with hostilities against Mexico. USA would lose lots of trade, too. There would be riots across USA & business owners would protest in fear of having their properties/businesses burned, looted & destroyed. USA would look like Russia (tRump would LOVE that) & don't forget that Russia & China might decide to side with Mexico and join in alongwith those nations tRump called Sh*tholes... THEN WHAT? And do you even THINK our Congress will go along with tRump? Ha, don't believe it!
