There is water. The Rio Grande. That’s why they were once called “wet backs”. But it’s not PC to say that now.
Thanks for the reminder.
If the Rio Grande is a coast then the Coast Guard should guard it against invasion from foreign nationals.
Like cyberwar , interference with satellites in space and identify theft aren’t like lines of uniformed soldiers facing each other in WWII, our borders being breached by invaders is merely an update on warfare, too. Stalin and others used women and children held in front of armed troops as a tactic like today’s children cynically used as photo op props.
