On the nuclear issue, the first point is that the entire world must recognize that Iran does not seek a nuclear weapon, nor shall it seek a nuclear weapon.
Nuclear disarmament and non-proliferation are not utopian ideals. They are critical to global peace and security.
The United States government first learned of the diversion of the W-88 nuclear warhead design in late 1995.
Nuclear transplantation is a technique that has enormously facilitated the analysis of these interactions between nucleus and cytoplasm.
Nuclear apocalypse - who do you need? Actors are probably not top of the list. What can I do for you? I can pretend to be somebody who can grow you some nice crops.
We're simply trying to say that Congress has a constitutional role to approve any deal, to make sure that Iran never gets a nuclear weapon. Not today, not tomorrow, not ten years from now.
Humanity has nearly suffocated the globe with carbon dioxide, yet nuclear power plants that produce no such emissions are so mired in objections and obstruction that, despite renewed interest on every continent, it is unlikely another will be built in the United States.
My U.N. five-point plan focuses on preventing proliferation, strengthening the legal regime, and ensuring nuclear safety and security - an effort that was given good momentum by the Nuclear Security Summit held in Seoul earlier this year. The world is over-armed, and peace is underfunded.
U.S. nuclear weapons that are available for presidential use are targeted against broad ocean areas.
The AEC scientists were so narrowly focused on arming the United States for nuclear war that they failed to perceive facts - even widely known ones - that were outside their limited field of vision.
The trick in nuclear strategy is to maintain stability by balancing potentials and thus to discourage events from converting the hypothetical to the actual.
It is most regrettable that nuclear energy is being harnessed for making nuclear weapons.
The catastrophic humanitarian consequences of any use of nuclear weapons require that it be treated as a top priority. Disarmament will work better than any alternative in reducing the risk of use.
I think God has blessed this country with enormous natural resources, and we should pursue all of the above. We should be developing oil, and gas, and coal, and nuclear, and wind, and solar, and ethanol, and biofuels. But, I don't believe that Washington should be picking winners and losers.
Football isn't nuclear physics, but it's not so simple that you can make it simple. It takes some explaining to get it across.
My red line is Iran may not have a nuclear weapon. It is inappropriate for them to have the capacity to terrorize the world. Iran with a nuclear weapon or with fissile material that can be given to Hezbollah or Hamas or others has the potential of not just destabilizing the Middle East.
A nuclear power reactor is just a fancy way of boiling water.
I wondered whether the nuclear transfer techniques could be used to introduce purified macro-molecules into an egg, and hence into embryonic cells.
If we take into account the existence of our planet, we have to recognise that we are guests that spend a short and very determined period in this world, and all we leave behind is nuclear waste.
When I'm looking for a leader who's gonna sit across the negotiating table from a nuclear Iran, or who's gonna be intent on destroying ISIS, I couldn't care less about that leader's temperament or his tone or his vocabulary. Frankly, I want the meanest, toughest son of a gun I can find.
Chemical weapons, biological weapons, and nuclear weapons should never be used.
There's no way you can possibly intellectually justify, 'Well, it's okay for the Western Judeo-Christian countries to have nuclear weapons, but not for a country like Iran.' That logic goes nowhere fast.
Nuclear missiles don't discriminate on party lines when they land.
Nixon did have a secret plan, and I knew that it involved making threats of nuclear war to North Vietnam.
The threat and use of violence is stimulating nuclear proliferation along with jihadi terrorism.
The only thing that kept the Cold War cold was the mutual deterrence afforded by nuclear weapons.
Until the last nuclear weapon is eliminated, more must also be done to reduce the risk of a detonation. Nuclear-armed states should reduce the number of warheads on high alert and be clearer about the actions they are taking to prevent accidents.
We should not approve an agreement that fails to prevent Iran from developing nuclear weapons and does nothing to address Iranian behavior that threatens our allies and our interests.
Growing up during the Cold War, I remember the seemingly imminent threat of nuclear war. In primary school we were taught to 'duck-and-cover' for protection. But even as children hiding under wooden desks, we recognized the inadequacies of this strategy.
We are determined to provide for the nuclear fuel of such plants inside the country, at the hands of local Iranian scientists. We are going to follow on this path.
Japan learned from the bombings of Hiroshima and Nagasaki that the tragedy wrought by nuclear weapons must never be repeated and that humanity and nuclear weapons cannot coexist.
In 1974/75, I spent a sabbatical year with Professor Vince Jaccarino and Dr. Alan King at the University of California in Santa Barbara to get a taste of nuclear magnetic resonance. We solved a specific problem on the bicritical point of MnF2, their home-base material. We traded experience, NMR, and critical phenomena.
Hillary Clinton famously talked about how raising a child takes a village. Except our society isn't set up that way. We're organized in nuclear units, and a single mom can ask her friends only so many times for help picking up the kids.
The international community must do a better job of controlling the risks of nuclear proliferation. Sensitive parts of the nuclear fuel cycle - the production of new fuel, the processing of weapon-usable material, the disposal of spent fuel and radioactive waste - would be less vulnerable to proliferation if brought under multinational control.
Am I not correct in saying that Iran has never voiced that they are developing a nuclear weapon, nor do they have any intention of using a nuclear weapon against the United States? That's never actually been voiced. I don't know where that has come from, but it hasn't been from Iran.
Our goal is simple: to stop Iran from obtaining a nuclear weapon.
