If they’d have closed the border years ago, they wouldn’t have the need or the excuse.
Using them on the border was nothing but an EXCUSE to do trial runs for actual use against American citizens. Make no mistake. The gov’t just wanted a little practice first.. Has the gov’t ever really cared about the border anyway? Hell no. The gov’t will have fun with them until one collides with a commercial airliner over a major city. They’ll get hijacked by hackers too just like the one lost to Iran.
