It HAS to be the mil that does it, or at least major military presence to protect contractors working on the Wall. The cartels and (((their backers))) have far, far too much to lose to allow the Wall to be built.
It was always going to be the military.
Saw an article on BB/ZH today that mil drawdown planned for border. I don't believe that for a second - though maybe specific units, but will be replaced by many others, more suited for specific tasks/location(s).
The Plan is fucking awesome, enjoying the show!
