There should be about dozen US government charter flights or military flights a day from the border area directly to Honduras. You cross the border illegally, you go to Honduras the same or next day. What? You’re from Guatemala or El Salvador? Tough shit invader, Honduras is close enough, catch a bus home from there.
There is a decent air strip, mil base, once used by the US Military north of Tegucigalpa (Comeagua?). Good enough spot for our new deportation hub.
If we cannot push dinky broke Honduras around to make this happen, then we should hang it up, we’re done.
I would like to add one thing to what you are proposing. Send navel vessels down to that area with Marines on there to make everybody very very nervous. Let them worry about a real invasion and take down.
