“We need to build large catapults and heave bags of gold at the dragon.”

“So you’re suggesting we throw money at the problem?”

“Precisely, sire.”

And the reason, of course, is that DHS really has no idea what to do to secure the border, aside from throw money at it.

Now that you mention it… maybe that’s a better solution.
Throw money at the border, so immigrants can come by and pick it up.
Once they have money, they’ll turn around and walk back home.

(and promptly blow it all on worthless shit and come back for more)

…Florida seems to have a surplus of hungry man-eatin’ ‘gators (actually woman-). How ’bout relocating a few thousand of ‘em to the Rio Grande River?

Then a bunch of the troops can remain home on their jobs so that illegals won’t be hired to replace the Guard members on duty at the border.

It seems workable to me. Cheap and effective.
