When the US used "weather balloons" to spy

The US used "weather balloons" to spy on China and the Soviet Union in 1956. If one wanted to argue that China is evil and vicious because it sent a balloon to spy on the US, that inconvenient fact would show the argument to be hypocrisy.

I do not think it was particularly bad of China to use balloons to snoop on a rival, or that it was particularly bad of the US to do likewise. I don't condemn China for snooping. I condemn China for its horrible repression and brainwashing of Uygurs in Xinjiang, for its horrible repression and crushing of the 7-8 million people of Hong Kong, and its plans to conquer Taiwan so as to repress and crush the 23 million Taiwanese.

I also secondarily rebuke China for its blatant plans for economic colonialism around the world. This is no better when China does it than when the US does it.
