I'm missing something - why would you be wanting to intercept balloons over someone else's airspace? The 2023 incident was in US (and Canadian) airspace.
Sorry, I should have explained it: you want to intercept a spy balloon before it enters your airspace, not after it has already entered and possibly gathered any information.
