Ukraine is the one US media has been trying to pin this on.

I'm gonna have to disagree with that (interpreting US media as Reddit because I don't watch internal US media): Ukraine is the backup compromise for people who don't buy that Russia did it. I think they still want people to think Russia did it. Officially, the USA says there was no risk that the Chinese weather balloon was a spy balloon or anything other than a weather balloon, but they are still pushing the spy balloon angle. I think blaming Ukraine is like when they blamed Donetsk for MH117. The primary story is that it was Russia, 'but alright if you keep insisting on being sceptical we'll admit it was Ukraine, but it was rebels in Ukraine so they really had no say in the matter.' 'Russia did Nordstream, but alright if you keep insisting on being sceptical we'll admit it was us, but it was Ukraine acting on their own, because they're angry, who can blame them. So we really had no say in the matter.'
