Biden has been allowing it for a while now, but this time the public found out. The incompetent press secretary’s fumbling of the question whether other balloons from China have been floating over the US under before under Biden makes it pretty clear that the answer is “yes”.
The military is not incompetent, its commander is incompetent and potentially compromised to China.
For the record, I don’t think there is any significant military value in the spy balloon, I think that the significance is in the disrespectful slap to the face of Biden by the Chinese on the eve of a summit between the two countries.
There is no respect and no concern on Xi’s part for the US under Biden.
The real news in this story is that China chose to chill relations as it furthers its designs on Taiwan. The cancelled trip of Blinken is very real (only decision possible) and very intended by the Chinese.
Oh for a leader.
