Considering the US has continuously threatened North Korea's existance, who can blame them for wanting a nuclear deterrant?
MAD (Mutual Assured Destruction) prevented war on many occasions. Possessing nukes isn't enough for MAD. A country also has to have the means to deliver them. North Korea isn't there yet.
I agree its like North Korea will sell their nuclear secrets to the highest bidder. Besides WMDs, the country produces little else of value.
As far as the NPT is concerned, that agreement was signed nearly 40 years ago and the main violators are the US, Russia, UK, China and France.
Under the terms of that agreement, nations that did not possess nuclear weapons agreed not to pursue them in exchange for the right to peaceful nuclear technology. Nations that did possess nukes (US, Russia, UK, France, China) were supposed to rid themselves of their nuclear arsenals. Instead, the nuke nations have violated the terms of this agreement by not only maintaining their nukes, but by developing new types of nukes, and in the case of the US, officially drawing up plans to use nukes againt non-nuke nations.

Also for a laugh:

As far as anyone knows, Iran has respected the main pillars of the NPT. It is not and never has been in violation of the NPT. Iran only failed to comply with
voluntary as in non-compulsary parts of the treaty. The IAEA was supposed to help countries like Iran develop peaceful nuclear technology while ensuring NPT compliance.
North Korea's decision to withdraw from the NPT was the equivalent of declaring its intention to develop nuclear weapons just as India and Pakistan did before they tested their nukes.
Israel has nukes, but never signed the NPT.
In theory all NPT violators and non-signatories should face sanctions. Instead only the NPT violators and non-signatories the US doesn't like and a few who are in compliance face the threat of sanctions.
The NPT is a joke and is as good as dead. North Korea's test just made it official.
