Is it me? When NBC reports something and uses the words, "military surveillance", I get the feeling they are doing a hit job on Trump. As if military surveillance is something ominous or evil. While I have absolutely no problem with the military being on our border, the Rat base does. So this was written to upset Rats.
As for fewer people appear to be crossing illegally, perhaps that has something with the added military and cameras, and oh yeah, the flu.
Fewer people crossing should have nothing to do with the planned border security construction, it needs to continue as planned.!
