When the nukes start flying they will take out the east and west coast first.
Regrettably, mate, IF nukes are ever deployed, it'll insure MAD across our beautiful planet Earth. It'll destroy our planet and end life as we know it. Survivors, if there are any, will eventually die, too.
Mutual assured destruction refers to the concept that two superpowers are capable of annihilating each other with
nuclear weapons, regardless of whether they are attacked first.
In theory, under mutual assured destruction, a nuclear attack by one superpower will be met with an overwhelming nuclear counterattack by their target — using early warning systems, automated missiles, airborne nuclear bombs, and missile-armed hidden submarines. This will lead to the complete destruction of both. As such, mutual assured destruction — often abbreviated as MAD — is part of the military strategy of deterrence, in which one adversary threatens another with a reprisal if they attack first.
After the 1960s, mutual assured destruction was the main nuclear doctrine — the stated military principle — of
the Cold War between the United States and the Soviet Union in the late 20th century. It is still in operation today between the nuclear forces of the U.S. and Russia, and experts have suggested that MAD is the reason that small states such as Israel are thought to have developed nuclear missiles. (Israel is deliberately ambiguous about whether it has them.)
According to a 2007 study in the journal
Asian Affairs: An American Review,
China, the third nuclear superpower, does not have the capacity to threaten true mutually assured destruction because its relatively small arsenal of nuclear missiles does not have a credible "second strike" capability, which would be needed to automatically respond to a nuclear attack.
But complete annihilation of an enemy is not the only way MAD comes into play. For instance, "rogue states," like
North Korea and Iran, are striving to develop nuclear missiles, perhaps in the hope that they will be able to at least inflict severe damage on an enemy before they are annihilated by a nuclear counterstrike — a partial application of the MAD doctrine, according to a 2019
analysis by the U.S. Department of Defense.
The term "assured destruction" was first used in the 1960s by then-U.S. Secretary of Defense Robert McNamara, who served in the Kennedy and Johnson administrations. But
according to Britannica, the longer phrase "mutual assured destruction" was coined by an opponent of the policy, American military analyst Donald Brennan, who argued that it did little to secure U.S. defense interests in the long-term.
McNamara estimated that a nuclear strike force with the equivalent explosive power of 400 megatons of TNT — a "few hundred" missiles, as some military planners said — was needed to ensure an effective nuclear deterrence, according to the
Brookings Institution.
But that MAD number rapidly increased, and by the time of the Carter administration in 1977, military planners argued that the U.S. needed 2,000 nuclear warheads. But about the same time officials said the U.S. needed to reduce its nuclear arsenal to 5,000 warheads, and in the mid-1990s officials talked of reducing the number again to 2,500, so clearly many more had already been built. (These numbers far outstrip the number needed to do catastrophic damage to the planet. For instance, a 2012 study by the Bulletin of the Atomic Scientists found that just 100 nuclear detonations of the size that struck Hiroshima and Nagasaki would usher in a planetary nuclear winter, which would drop temperatures lower than they were in the Little Ice Age,
Live Science previously reported.)
Although no one has tested the concept of mutual assured destruction by nuclear weapons, it seems to have prevented war between superpowers since nuclear weapons were invented in the 1940s. But it also led to periods of the Cold War when both the U.S. and the Soviet Union spent huge amounts of money to develop nuclear weapons and the methods to use them.
Experts in nuclear weapons arsenals estimate that the United States had more than 30,000 nuclear warheads in service at the height of the Cold War in the 1960s and 1970s, while the Soviet Union may have stockpiled more than 40,000 warheads by the late 1980s, according to
BBC News.
