alt Hacker NewsI wonder if anyone ever did the math on whether trying to maintain a barrier at the Darian Gap with occasional failures was really a better financial choice than teaming up with South American countries to drive screwworms to extinction.

I think the issue is that you would have to push the barrier across the entire South American continent, which is twice the distance of the US-Mexico border and also crosses the Amazon where there is basically no infrastructure.
Yes, they did because various countries have talked to the US about expanding it. The problem is that South America is an enormous place, whereas Panama is a narrow isthmus. It could have been done with some amount of money, but that opportunity ended in 2010 at the latest.
