核武器 解决方案

The only way to completely eliminate nuclear risks is to eliminate nuclear weapons from the planet.


The only way to completely eliminate nuclear risks is to eliminate nuclear weapons from the planet.


US nuclear weapons are on hair-trigger alert.

大约9,500 nuclear weapons are hidden away in bunkers and missile siloes, 仓库储存, at airfields and naval bases, and carried by dozens of submarines across the world.

A single warhead can demolish a city center. A full-fledged nuclear war would threaten life as we know it.

But with the right policies and safeguards, we can help protect against mistakes, 事故, and poor decision-making—and we can work toward a world free from the nuclear threat.

Nuclear weapons are meant to deter nuclear attacks from other countries. 然而, current policy allows the United States to begin a nuclear war by being the first to use nuclear weapons in a conflict—in response to a non-nuclear attack by North Korea, 俄罗斯, 或中国.

A "no-first-use” policy would take this option off the table. The United States could pledge that it will never be the first to use a nuclear weapon, regardless of the circumstances. Doing so would reduce the risk of miscalculation during a crisis, and limit the possibility of a smaller, non-nuclear conflict escalating into a nuclear one.

没有不, the US public is at greater risk of a devastating attack, either because another country—fearing the US will use nuclear weapons— decides to escalate first, or the United States chooses to start a nuclear war, leading to cataclysmic retaliation.


在美国, the president is singlehandedly responsible for the decision to launch a nuclear weapon. They are not required to consult with anyone, and no one carries the authority to stop a legal launch order once given.

This system of control (known as “sole authority”) isn’t the only way to handle launch decisions. 其他 officials could securely 被包括 在决定中, providing checks and balances and a basic defense against mistakes, 事故, 失误, 和鲁莽.


Currently, 800 nuclear-tipped 导弹 in the US heartland are kept on “hair-trigger alert.” If sensors show an incoming nuclear attack that threatens these 导弹, it’s US policy to alert the president, who would need to order their almost immediate launch to prevent them from being destroyed—before the attack is confirmed as real.

But sensors can be wrong. A long list of nuclear 比分接近的比赛—which include technical malfunctions, 误解, and plain bad luck—shows how close we’ve come to mistakenly starting nuclear war.

Taking these 导弹 off hair-trigger alert (or “de-alerting”) would immediately remove the risk of a mistaken or accidental launch, while preserving our ability to retaliate with 导弹 on submarines hidden at sea.


The United States is currently planning to spend an estimated $1.7 trillion dollars over the next three decades to maintain and replace its entire nuclear arsenal with new weapons, including nuclear-armed bombers, 导弹, 和潜艇.

Such a tremendous investment of money and effort is unnecessary. It also encourages 俄罗斯 to build more capable weapons of its own, accelerating an emerging and destabilizing international arms race.

而不是, the United States should eliminate some types of nuclear weapons, refurbish the remaining weapons where possible, and make any necessary replacements without enhancing capabilities.

International agreements

总共 9个国家 possess nuclear weapons. Reducing the risk of nuclear war will require domestic policy changes in all those countries, as well as cooperation and verified agreements between them.

Diplomacy has a strong track record. Multiple treaties and agreements—and decades of dialogue and cooperation—helped reduce US and Soviet arsenals from a high of 64,000 warheads in the 1980s to a total of around 8,今天的000. Unfortunately, today international nuclear arms control is in trouble.

The Biden administration’s 5-year extension of the New Strategic Arms Reduction Treaty (New START) with 俄罗斯, is the last remaining bilateral arms control agreement between the two countries, but the US and 俄罗斯 seem to be 在小路上 to letting the treaty expire in 2026 with no replacement, Negotiation of a new agreement, or renewal of the current agreement would reduce nuclear risk but will be difficult to achieve. A more feasible option is for the US and 俄罗斯 committing to abide by the limits set out in the treaty once the Treaty expires.

分别, China strongly prefers international approaches to arms control rather than bilateral agreements. It is willing to work with the US government to bring the Comprehensive Nuclear Test Ban Treaty into force and negotiate a Fissile Material Cutoff Treaty. Both agreements would make the United States and the world more secure.
