Smokin Joe cautions:
"While I agree in principle, at some point there will be a confrontation that will leave bodies on the ground."
Joe, you know as well as I do that the invasion will not be stopped (or even slowed) UNTIL there are "bodies on the ground".
Regardless of what happens afterwards.
Just sayin'...
Again, I agree, but the focus should be on those bodies not being Americans as much as possible.
FWIW, the tech to follow and interdict the militias is firmly in the hands of the USBP, if the orders are given to interdict the militias (likely), then the effort to do so will take precedence over guarding the border, and those bodies will all be American, while the invaders skate through. Just a realistic viewpoint. In the absence of the militias and USBP coming to at least local agreements to look the other way as the militias operate or even share data, unofficially, that is the most likely scenario. That requires people on the 'inside', raking risks, to ensure any militia success.
