Seventeen years after the Cold War, how can it be in the Unites States' national security interest for the President of Russia to have only a few minutes to decide whether to fire his nuclear weapons or lose them in response to what could be a false warning?

The Iranians know that if they develop nuclear weapons, they will be in tremendous jeopardy from military capabilities of their neighbors and of the United States. I am not predicting what will happen in 2013, but I do think it is a crucial year. I hope we can make it clear to the Iranians that we do not object to them having peaceful use of nuclear power. But when they enrich Uranium to a 20 percent level, people think they are going for the bomb. Their uranium enrichment program is a real danger.

Leadership must be established from the top down.

Senator Biden was correct by calling for more to look into Governor Cuomo's defense policy. It is clear to me, by researching the governor's record on the issue, that he would be a wildcard on national defense issues.

I don't know how you make a record on liberal and conservative these days. We've had a conservative Republican Congress, so to speak, and a conservative president, and we've run up one of the most astounding deficits in the history of our nation.

Some people think we will see a nuclear explosion in Europe or the United States within the next 10 years. Will it happen? Sure, it's possible. But I think we can greatly diminish that risk. The only way you can do that is through cooperation, and it has to be global.

You have to pay the price. You will find that everything in life exacts a price, and you will have to decide whether the price is worth the prize.
