I think most of us assumed they had them - now they’ve proved it. One good thing - sounds like China is NOT happy with them. (Neither is anyone else - except, probably, Iran.)
Instapundit has some good links.
Wizbang is following a rumor that they may be about to do a second test.
My biggest worry for the US is that they might sell their nukes to someone… like Iran.

I don’t take much stock in China’s “outrage.”
I am absolutely convinced that North Korea is her, China’s, cats’s paw.
Can’t prove it, but its what I think.

An Iranian bomb is more dangerous because of its trimphalist fall-out in the islamo Axis.
