They’re not at high altitude. They’re actually pretty stable.

That’s not at all true…

It’s been done many, many times before… the Japanese were doing it all the way back in WWII…

They don’t, actually. For camera or radio imaging, sure, but for signal scooping, you need to be in atmosphere due to the way radio waves reflect off the ionosphere. That’s why the US is flying radio signal intelligence aircraft in the Black Sea instead of just using satellites to intercept Russian radio communications and gather intelligence.

Try being a little more educated before making wild assertions.

It is worth noting that it is possible for stratospheric balloons to navigate with purpose within the chaos of different wind currents by controlling their altitude in order to choose which current to ride at a given moment. This is a thing that has been done. How difficult it is I leave to the nation states that might want to sense something they can’t detect from satellite altitudes (like magnetic fluctuations?) —or to the ham radio enthusiasts whose $100 Arduino balloons attract the ire of very expensive jet-fired munitions.
