They're already off to a bad start with the Chinese surveillance balloon hovering over the US in the first place. Incredibly awkward. This kind of thing is not normal. That's why it's front page news. Well within rights to shoot it down or render it inoperable.
It should be shot down if the Chinese won't be up front about what it is and why it's here and continue to deny that it's theirs.
It's in US airspace with no apology or intention by the Chinese to remove it. Shooting it down is totally reasonable
