I’d like to see that promise of a wall across 2000 miles. That would be a trick with the natural features of parts of the border. You take it as given that Abbots floating barrels are going to be effective? I don’t. And it is a big lie that Trump didn’t negotiate to get the wall done, one that only someone who was born yesterday would believe.
The Chinese several thousand years ago build a wall, across varying terrain. I’m sure we can do it with today’s technology
