A Quote by Carl Sagan
The prediction of nuclear winter is drawn not, of course, from any direct experience with the consequences of global nuclear war, but rather from an investigation of the governing physics.

Remember that in any major nuclear war, the first strike destroys the country that attacks; it's been known for years. The first strike of a major power is very likely to cause what's called nuclear winter, leads to global famine for years and everything's basically gone. Some survivors straggling around. Could [Donald Trump] do it? Who knows.
It has been known for some time that a major nuclear war might lead to nuclear winter that would destroy the attacker as well as the target. And threats are now mounting, particularly at the Russian border, confirming the prediction of George Kennan and other prominent figures that NATO expansion, particularly the way it was undertaken, would prove to be a "tragic mistake," a "policy error of historic proportions."
Teller contended, not implausibly, that hydrogen bombs keep the peace, or at least prevent thermonuclear war, because the consequences of warfare between nuclear powers are now too dangerous. We haven't had a nuclear war yet, have we? But all such arguments assume that the nuclear-armed nations are and always will be, without exception, rational actors, and that bouts of anger and revenge and madness will never overtake their leaders (or military and secret police officers in charge of nuclear weapons). In the century of Hitler and Stalin, this seems ingenuous.
I've been working with Global Zero. They are a great organization leading the resistance against nuclear war and the elimination of nuclear weapons.
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.
The greatest threat to U.S. and global security is no longer a nuclear exchange between nations, but nuclear terrorism by violent extremists and nuclear proliferation to an increasing number of states.
With the nuclear threat we know that if sufficient weapons are used, human civilization - all of humankind - could be extinguished literally by "nuclear winter." So we have to see ourselves as part of the ultimate human group, just as we have to do with global warming.
Many foolish people believe that nuclear war cannot happen, because there can be no winner. However, the American war planners, who elevated U.S. nuclear weapons from a retaliatory role to a pre-emptive first strike function, obviously do not agree that nuclear war cannot be won.
If we are to assume that North Korea becomes a nuclear-power state, of course the danger of having an all-out nuclear war, that possibility is very slim.
Much as Cold War nuclear strategists could argue about winning a nuclear war by having more survivors, advocates of a Global Warming War might see the United States, Western Europe, or Russia as better able to ride out climate disruption and manipulation than, say, China or the countries of the Middle East.
There has been a transition from a nuclear-annihilation scenario to an isolated-terrorist-nuclear-bomb scenario. But we're still locked into a mind-set that nuclear war would be so overwhelming that any kind of preparedness would be futile.
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.
...nuclear threats and nuclear weapons are the last argument of weak, stressed and irresponsible politicians. People must act very quicky to stop the movement to nuclear war.
Since the end of the Cold War two main nuclear powers have begun to make big reductions in their nuclear arsenals. Each of them is dismantling about 2,000 nuclear warheads a year.
I started out in nuclear physics. But after I became more sensitized to the environmental and health implications of the nuclear system - I was being trained to be the first women in the fast-breeder reactor in India (and was in it when it first went critical) - I didn't feel comfortable with it. So I went into theoretical physics.
In many places around the world, all over the U.S. and Europe there are active nuclear power plants. And for many years during the Cold War the threat of nuclear war was a permanent fear. There's always the concern that human kind is biting off more than they can chew in harnessing nuclear power.
