That could be true. If it is true, then our President has blatantly lied to us once again. His spokesperson, John Kirby said plainly to the press that our government didn't know who was behind the drones. But, why should we be surprised at Biden lying.................
If it is them, they could tell us it is them without telling us specifically what they are doing. I think most reasonable people understand that the government has to do some things that can't be made public.
PS - Just saw Mayorkas as I was typing this saying essentially the same thing. I sure hope it is a lie rather than incompetence.
