Kinda hard to cover up that sort of thing, considering the number of telescopes Americans have. Plus this whole internet thing.
It is kinda comforting to actually see the possible enemy's "surveillance systems" though. They have a balloon, we have the U-2. Nah, we don't just ask Bono, this U-2 is a US Army spy plane we've used since the 50s. The Air Force has the SR-71 Blackbird.
Of course, Biden is in a "damned if you do, damned if you don't" situation with Republicans, because it is always easier to be an armchair quarterback than actually the one responsible for the decisions being made.
