Needs to be 800 armored vehicles, tanks and bradleys in full view of the border. When this 'caravan' is a hundred miles out constant overflights with Mexico's permission or not. If they plan on coming in San Diego's port of entry, an M1A1 parked in each lane pointing into Mexico should blunt any bumrush like they pulled on the southern Mexico port of entry.
Doubtful 800 guys standing around a bunch of tents will deter anything. South Americans are used to seeing their federale police and Army in full battle rattle all the time.
The war to “de-white” the US started at least 100 years ago.
People immigrating here from eastern Europe was the beginning of the end.
How did South America get involved?
