It's more likely a coordinated event to get people to talk about something other than covid and the last 3 disastrous years. Lets be honest here, neither china nor the US wants people asking uncomfortable questions about covid. Now that the covid era appears to be over, what better way to distract people than "war".
They did the same thing with 9/11. Uncomfortable questions about 9/11 was overshadowed by war and iraqi "wmds". Eventually people forget or move on.
Call me a cynic, but china ends covid lockdowns and all of a sudden we get "surveillance" balloons. And the entire media apparatus has us talking about silly balloons instead of wondering what the last 3 years of covid was about. My guess was a staged "terrorist" attack somewhere to transition us from the covid news cycle. Turns out we got balloons instead. Whatever works in the end.
