Our - our friends can't trust us anymore. You know, Ukraine was a nuclear-armed state. They gave away their nuclear arms with the understanding that we would protect them. We won't even give them offensive weapons.

Today, India is a nuclear weapons state.

What we have to remember is we want to utilize the tremendous intellect that we have in the military to win wars. I've talked to a lot of the generals, a lot of our advanced people. And believe me, if we gave them the mission, which is what the commander-in-chief does, they would be able to carry it out.

Crimea was not a non-nuclear zone in an international law sense but was part of Ukraine, a state which doesn't possess nuclear arms.

A world without nuclear weapons would be less stable and more dangerous for all of us.

Long before the terrifying potential of the arms race was recognized, there was a widespread instinctive abhorrence of nuclear weapons, and a strong desire to get rid of them.
