Perhaps we could consult with Israeli experts regarding how best to find and prevent dangerous cross territorial tunnel gateways to smuggling of contrabands, drugs illegal aliens etc.....

They have some decent engineers and planners and builders and hard workers down there.
Gotta wonder why their country is such a sh!thole.

* So throwing billions of dollars at Trump’s wall & serenading how impressive it is, is self defeating- don’t you think? Years back Brazilian diggers dug into a bank, whether they were ever caught is an ongoing guess.

You do realize Biden's administration that said it wouldn't spend $5 billion on protecting our southern border because it was too much money to spend to keep people out of our country, now wants to send $40 billion to Ukraine to help them keep the Russians out of their country?
If it was the other way around maybe we wouldn't have the problems we do.
