Re: The "weather" balloon
I can guess at a few reasons for the US to shoot it down, even after it traversed the country:
- to see what it was capable of doing
- to see what the gear looks like, assuming it wasn't just consumer grade electronics
- to assess what it was actually doing
- to be in a position to report to the world what the US knows about it rather than what they think it was about
- and yes, also to demonstrate domestically that they were doing more than wringing their hands
It's also possible Biden doesn't like being toyed with.
