I know, it’s a nuclear option. Seriously shouldn’t put that card down right off. And yeah, hasn’t gone well for any central or south american government that the US has destabilized or overthrown due to some large corporation’s interests. But as all this garbage escalates, bringing up the possibility could make owners and shareholders squirm a bit. It hurts them financially, the only thing that would make them care. People who Trump might (might, small chance) listen to. But before that point? Those companies can produce all kinds of things. Doesn’t mean Canada or Mexico have to let those goods go out across their borders. Their trade agreement has been torn up by Trump again. And you know that bureaucracy is complicated, things get held up in customs sometimes, occasionally for very very long times. Paperwork gets lost… When companies here in the US are screaming about their supply lines breaking down again, now because of HIS stupid tariff war, there will be some negative political fallout. Trump’s ego and image are vulnerable things despite all the bluster. He won’t back down, but he could pivot to something else and let this nonsense drop.
