The leading Republican candidates for president want to unleash military strikes inside Mexico against the cartels — with or without Mexico’s permission — and have not voiced concern about the likely blowback. Donald Trump has promised a naval blockade in a second term. At the debate he skipped last week, rivals promised to counter the border “invasion” with assets shifted from Ukraine. Florida Gov. Ron DeSantis vowed to send special forces into Mexico “on day one.”
There will still be a black market to crack down on. Those cartels won’t just say “oh I guess that’s it”.
Keep your enemies closer. We still have black markets but when they are next to legal markets, its easier to track them down.
