A Quote by Steven Weinberg
It's very difficult to convince other countries that they shouldn't pursue nuclear weapons programs if we ourselves are actively developing a component of a strategic defense system.

One of the greatest concerns that I had when I became President was the vast array of nuclear weapons in the arsenals of the United States and the Soviet Union and a few other countries, and also the great proliferation of conventional weapons, non-nuclear weapons, particularly as a tremendous burden on the economies of developing or very poor countries.
What is the only provocation that could bring about the use of nuclear weapons? Nuclear weapons. What is the priority target for nuclear weapons? Nuclear weapons. What is the only established defense against nuclear weapons? Nuclear weapons. How do we prevent the use of nuclear weapons? By threatening to use nuclear weapons. And we can't get rid of nuclear weapons, because of nuclear weapons. The intransigence, it seems, is a function of the weapons themselves.
I call on all scientists in all countries to cease and desist from work creating, developing, improving and manufacturing further nuclear weapons - and, for that matter, other weapons of potential mass destruction such as chemical and biological weapons.
As far as U.S. intelligence knows, Iran is developing nuclear capacities, but they don't know if they are trying to develop nuclear weapons or not. Chances are they're developing what's called 'nuclear capability,' which many states have. That is the ability to have nuclear weapons if they decide to do it. That's not a crime.
The basic problem with the Non-Proliferation Treaty is there's no teeth in it, no penalties for countries that don't comply. Worse, as you say, the very naïve structure of the NPT has actually made it helpful for countries who want to acquire nuclear weapons. Iraq, North Korea, Iran, all used the NPT to build up their nuclear programs.
I don't want to use the term "nuclear weapons" because those people in Iran who have authority say they are not building nuclear weapons. I make an appeal to the countries who do have nuclear weapons. They don't consider them a nuclear threat. But let's say a country that doesn't have nuclear weapons gets involved in building them, then they are told by those that already have nuclear weapons that they oppose [such a development]. Where is the justice in that?
The cavalier casual way that Donald Trump talks about nuclear weapons is not only frightening but it goes counter to more than 70 years of bipartisan, presidential leadership of Republicans and Democrats who believed that we have to prevent other countries from getting nuclear weapons and we have to do what we can to decrease the number of nuclear weapons in the world.
It's very certain that North Korea is developing nuclear weapons for offensive purposes. They don't need nuclear weapons to defend their own country.
It is my view that there is no sensible military use for nuclear weapons, whether "strategic" weapons, "tactical" weapons, "theatre" weapons, weapons at sea or weapons in space.
There are nine countries in the world that have nuclear weapons. There are about 27,000 nuclear weapons total on the planet. The countries that have nuclear weapons deploy them ready for use and have doctrines saying that they would use them in certain circumstances.
My reading of the threat from Iran is that if Iran acquires nuclear weapons, it is an existential threat to the State of Israel and to other countries in the region because the other countries in the region will feel compelling requirement to acquire nuclear weapons as well. Now we cannot a second Holocaust.
The Kingdom of Saudi Arabia, like other countries in the region, rejects the acquisition of nuclear weapons by anyone, especially nuclear weapons in the Middle East region. We hope that such weapons will be banned or eliminated from the region by every country in the region.
It's clear to me that many weapons sales are very short-sighted. The U.S. and other arms-producing countries sell weapons for a variety of reasons, but most sales involve strategic interest or profit motivation, or both.
If you want to find weapons of destruction, you can find them all over the place. Take, say, Israel. There is a very great concern right now about proliferation of nuclear weapons, as there should be. Israel has a couple of hundred nuclear weapons and also chemical and biological weapons. This stockpile is not only a threat in itself but encourages others to proliferate in reaction and in self-defense. Is anybody saying anything about this?
Nuclear weapons continue to occupy a unique place in global security affairs. No other weapons, in my opinion, anyway, match their potential for prompt and long-term damage and their strategic impact.
I, who had been in favour of nuclear energy for generating electricity ... I suddenly realised that anybody who has a nuclear reactor can extract the plutonium from the reactor and make nuclear weapons, so that a country which has a nuclear reactor can, at any moment that it wants to, become a nuclear weapons power. And I, right from the beginning, have been terribly worried by the existence of nuclear weapons and very much against their use.
