Some day, somebody is going to have to start talking about what happens to us all a decade from now if we let these North Koreans and the Iranians go forward with their nuclear weapons program.

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

We have an active program. We have nuclear weapons, we are a nuclear power. We have an advanced missiles program.

A nuclear program has arguably worked as a deterrent for North Korea and other states - would Moammar Gadhafi have been deposed and summarily killed if Libya had had nuclear weapons? Iranians might not think so.

We are categorically against proliferation of nuclear weapons.

Today, India is a nuclear weapons state.
