I agree and disagree. I really don't know where I stand on this issue. But I think the big difference is North Koreas public rhetoric is pretty malicious. I think it's mostly political posturing, but to be fair they did just release a youtube video last week about how they are going to rain down fire on major US cities now that they have the weapons to do so. They stated their missile program and nuke program now gives them the ability to strike the US. Plus, they can already attack the South anytime they want. They are still at war with South Korea and American. Again, I believe it's mostly harmless posturing, and more for their own people than as a threat to the world, but none the less that does make them a difference. When you combine their space/missile tests with a now uranium trigger bomb test, it will only be a few years before they are able to combine those and have the range to hit as far as the West coast of America. Do I personally believe they will? No. Even China is for the first time condemning them after this most recent test.

Pakistan and India have nukes and long range missiles too... but they aren't threatening to burn other countries to the ground with them. That's the difference.

Again, not saying I disagree with your sentiment, but there are some differences to North Korea having nukes and what they say they are for, versus other countries who are like "we want them for defense too".
