They're already throwing Molotov cocktails in Mexico and attacking cops. They've declared their intent. They're carrying battle standards (their countries' flags), have burned our flag and have shields (women and children up front for sympathy) in front of them. This is an invading force. They are armed with rocks, Molotov cocktails and a few handguns, but an invasion nonetheless.

Here's a little Latin for you my Catholic friend...

Caedite eos. Deus suos agnoscet.
