It's violation of Arial space by a foreign electronic instrument equipped Arial object. Understanding Chinese resolve to show middle finger to all democratic nations should not be taken lightly. They have managed to put their such vehicles not only over our nuclear but defence assets as well and they deserve to be shot down right at the LAC or wherever encountered.
Chinese claimed "civilian" craft deviated by big margin as no one was onboard for steering and it has very limited control. So civilian that it always ended up following Indian defence installations both over Islands and mainland including LAC.
I don't deny that it is clearly a calculated move and not just "civilian balloons gone astray" but I feel it is being blown out of proportion. I doubt the balloons have a lot of tactical value, I think their whole purpose is just inflammatory. Something the Chinese can do for cheap to test response times and perhaps gather some meteorological data. The fact that these balloons are garnering public attention and causing such a lopsided expensive response is a huge added bonus.
