Biden says the 3 aerial objects shot down were not Chinese spy balloons

How can he say that ‘we don’t know what they are’ and at the same time say ‘we are sure they aren’t Chinese’? It doesn’t make any sense!

It's like saying "I don't know what kind of fruit this is, but I'm sure it's not a banana." Not defending his response, but it's not that strange.

Likely ham radio baloons

Three weren't. One was.

Other people also launch balloons, which wasn't a problem until spy balloons became a thing (along with other "unidentified" things). Now it's a problem, and they're going to start having to regulate more stuff.

tl;dr: this is why we can't have nice things
