This is different.
See, Drug cartels over here operate with the blessing and favor of our president. They are tightly connected.
If a cartel dared to ground a US flight. The US government would have a "free pass" to break all hell loose in Mexico, and Sheinbaum wouldn't have a way to stop it.
She doesn't want that in any way, so the message to the cartel bosses would be to be very careful in that respect.
Sure, there have been US citizens killed within Mexico here and there, but those can easily be attributed to local violence. And as retribution, Mexican government sends a couple of wanted criminals to the US.
Yeah, if a cartel actually used anti-aircraft weapons on a US passenger plane in US airspace? It wouldn't even matter if MAGA or the Democrats were in charge. The US would collectively lose its shit and spend the next 10 years and several trillion dollars retaliating against the cartels. The media would be ecstatic, because it would give them a decade of story arcs, starting with "our brave troops in uniform" all the way through to covering the eventual quagmire and anti-war protests. By year 6-8, editorial columnists would be writing columns reconsidering their initial support for the war.
Please, let's not do this.
