Imagine if Trump already knew about covid back when he started pushing for the wall to be built and the true purpose of it was to stop Americans running away. China has voiced concerns about the true origin of covid. And a tin wall never stood a chance of stopping Mexicans coming over yet might be more of an obstacle for Americans more used to a comfortable office work style of life?
Not saying I believe this to be true just a possibility that's out there like that covid was created to tackle climate change.( I've not seen the air so clear in my life)
