So I ask the nuclear powers to abandon the out-of-date thinking of the Cold War period and take a fresh look. Above all, I appeal to them to bear in mind the long-term threat that nuclear weapons pose to humankind and to begin action towards their elimination.
Joseph Rotblat

My own judgment of how the world is gonna end is that there will be a country led by a madman that will build a nuclear bomb with so much force, so much power, that it will be dropped somewhere on the face of this earth and that the earth will lose it’s place.
Evel Knievel

We are told that the possession of nuclear weapons - in some cases even the testing of these weapons - is essential for national security. But this argument can be made by other countries as well.
Joseph Rotblat

The case of Iran, a nuclear program that the Iranians admit was 18 years on, that we underestimated. And, in fact, we didn’t discover it. It was discovered by a group of Iranian dissidents outside the country who pointed the international community at the location.
David Kay

From a scientific perspective there is some indication that a nuclear war could deplete the earth’s ozone layer or, less likely, could bring on a new Ice Age - but there is no suggestion that either the created order or mankind would be destroyed in the process.
Herman Kahn

There are nuclear weapons in China, Iran, Korea and Pakistan. It wouldn’t take much to send a couple of warheads off on this planet somewhere that would cause a lot of environmental damage, then if you have got someone who wants to retaliate you have real problems.
Edward James Olmos

Yep, I did the whole thing and then realised i didnt have enough quotes. Thanks guys.

Several studies, and a number of public statements by senior military and political personalities, testify that - except for disputes between the present nuclear states - all military conflicts, as well as threats to peace, can be dealt with using conventional weapons.
Joseph Rotblat

Protecting Americans from nuclear terrorism rises above politics.
Lee H. Hamilton

If the militarily most powerful - and least threatened - states need nuclear weapons for their security, how can one deny such security to countries that are truly insecure? The present nuclear policy is a recipe for proliferation. It is a policy for disaster.
Joseph Rotblat

Hopefully, nations will refuse to accept a situation in which nuclear accidents actually do occur, and, if at all possible, they will do something to correct a system which makes them likely.
Herman Kahn

I think there are many times when it would be most efficient to use nuclear weapons. However, the public opinion in this country and throughout the world throw up their hands in horror when you mention nuclear weapons, just because of the propaganda that’s been fed to them.
Curtis Lemay

Let me remind you that nuclear disarmament is not just an ardent desire of the people, as expressed in many resolutions of the United Nations. It is a legal commitment by the five official nuclear states, entered into when they signed the Non-Proliferation Treaty.
Joseph Rotblat

The United States strongly seeks a lasting agreement for the discontinuance of nuclear weapons tests. We believe that this would be an important step toward reduction of international tensions and would open the way to further agreement on substantial measures of disarmament.
Dwight D. Eisenhower

Poorly secured nuclear material in the former Soviet Union, or secrets from a scientist in Pakistan could help build a bomb that detonates in Paris. The poppies in Afghanistan become the heroin in Berlin. The poverty and violence in Somalia breeds the terror of tomorrow.
Barack Obama

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

I most sincerely wish that the world in which we live be free from the threat of a nuclear holocaust and from the ruinous arms race. It is my cherished desire that peace be not separated from freedom which is the right of every nation. This I desire and for this I pray.
Lech Walesa

Today I can declare my hope and declare it from the bottom of my heart that we will eventually see the time when that number of nuclear weapons is down to zero and the world is a much better place.
Colin Powell

For this generation, ours, life is nuclear survival, liberty is human rights, the pursuit of happiness is a planet whose resources are devoted to the physical and spiritual nourishment of its inhabitants.
Jimmy Carter

Pro football is like nuclear warfare. There are no winners, only survivors.
Frank Gifford

Iraq is a long way from the U.S., but what happens there matters a great deal here. For the risks that the leaders of a rogue state will use nuclear, chemical or biological weapons against us or our allies is the greatest security threat we face.
Madeleine Albright

And also, we are providing, you know, a nuclear power plant in the north, two light water systems, so some 4 or 5 billion dollars we are providing to meet with North Korean requests on the condition North Korea will not produce a nuclear weapon.
Kim Dae Jung

I wonder if those people shown protesting the deployment of nuclear weapons to western Europe during the Reagan era are feeling appropriately stupid today. ‘Please don’t take away our precious Soviet Union! - We demand the annihilation of all life on Earth!’
Craig Bruce

Nuclear Definition
Ours is a world of nuclear giants and ethical infants. We know more about war that we know about peace, more about killing that we know about living.
Omar N. Bradley

You can’t be a real country unless you have a beer and an airline. It helps if you have some kind of a football team, or some nuclear weapons, but at the very least you need a beer.
Frank Zappa

All the waste in a year from a nuclear power plant can be stored under a desk.
Ronald Reagan

The world has achieved brilliance without wisdom, power without conscience. Our is a world of nuclear giants and ethical infants.
Omar N. Bradley

When we think of the major threats to our national security, the first to come to mind are nuclear proliferation, rogue states and global terrorism. But another kind of threat lurks beyond our shores, one from nature, not humans - an avian flu pandemic.
Barack Obama

I call upon the scientific community in our country, those who gave us nuclear weapons, to turn their great talents now to the cause of mankind and world peace: to give us the means of rendering these nuclear weapons impotent and obsolete.
Ronald Reagan

From John Cole of Balloon Juice:

And I will say it again, even though it always rankles people. Three Mile Island was a success. It was not Chernobyl. It was not nuclear armageddon. No, that does not mean I am pining for meltdowns everywhere, but I think some perspective is necessary. While it damaged the reputation of the nuclear industry, no one was hurt. No radiation sickness. No spikes in cancer rates. It was a disaster, but it was a success.

Excluding nuclear energy from the possible ways to fulfill our energy needs in the future immediately makes you an unserious person, in my book.
