North Korea is going to get away with keeping its nuclear weapons.

The larger picture here is that a North Korea with nuclear weapons adds to the larger proliferation risk.

It's very certain that North Korea is developing nuclear weapons for offensive purposes. They don't need nuclear weapons to defend their own country.

I don't like the fact that North Korea is testing nuclear weapons, and I don't like the fact that they're testing missiles and shooting them out in the sea in kind of an antagonistic fashion.

In the 1990s, the United States offered to help North Korea with its energy needs if it gave up its nuclear weapons programme.

North Korea has taught a great lesson to all the countries in the world, especially the rogue countries of dictatorships or whatever: if you don't want to be invaded by America, get some nuclear weapons.
