Important to not mistake “state” for “institutions” apart from what other people have said.
When Lenin talks about the state, he is talking about the state as a tool for imposing class domination. For example, using the police to quell protests and so on. He does not mean things like social safety nets will be done away with and we will live in a libertarian dystopia after the withering away of the state. There will still be institutions that for example ensure that everyone has adequate access to hospitals, clinics, etc. to ensure that healthcare is provided.
The balloon has been acknowledged by China as theirs. It’s probably not a spy balloon.
