Why is the US paranoid over a balloon?

Editor's note: Despite China's confirmation that it was a civilian airship that had deviated far from its planned course, a Chinese balloon that was used mainly for meteorological purposes was shot down by the US military on Feb 4. Why is the US so paranoia over a balloon that poses no security threat? What's behind the hyped-up balloon incident? Readers share their opinions.

US has no good reason to shoot down the balloon, the balloon held no security threat to civilian flights nor the residents on the ground, and the balloon is civilian property, the US medias and politicians are hyping up the matter, they just wanna to demonstrate that they are the hawkish toward China.
