Sadly, no. It probably will actually cost around $1B to drive screwworms back to the Darien Gap again and that's assuming the people in charge are planning that (they're probably not- why help poor countries?!) and capable of following a plan that already worked once (they're not). This number will balloon out of control and their nonsense plan to hold the line at Texas will be a disaster IF it ever even comes online as it's planned for late 2027. A preview of the planning genius.
