Yeah, IIRC the main "breach" happened during Covid as a result of the disruption caused by the pandemic, it's not something whose root cause can be blamed so easily on Trump. There was a program operating down in Panama to prevent the fly from spreading up through the narrow isthmus there by releasing sterile males and the supply chain disruptions broke it for a year or two, resulting in the flies getting through to Mexico where it's a lot harder to eradicate them.

Trump's cuts and chaos sure haven't helped the situation, though, and with dedicated effort it might have been possible to turn back the tide before now.
