One thing Trump tried to do after getting inaugurated was considering Mexican cartels terrorist organizations, and for that he was attacked by Sheinbaum for violating Mexico’s sovereignty. But, at least as far as I’ve read on the topic (whcih is not a lot to be fair), nobody actually explains why that’s the case. I mean at a glance you’d think the Mexican government would benefit from such an action, or at least I did. It’s pretty obvious to me I’m missing a piece of the puzzle, so does anyone here have it?

Edit: Thanks for the answers. Now it makes sense.
