No One Wins When Nuclear-Armed States Believe That ‘We Can’t Lose’

Nations engaged in wars with conventional weapons are not likely to hold back from using their most powerful weapons if they believe they are losing the war, and for too many countries in our world the most powerful weapons are nuclear. Countries committed to fighting a conventional war are also likely to be committed to the meme of “We Can’t Lose.”

A nuclear war could begin with the losing side in a conventional war making use of a small local tactical nuclear weapon to destroy the supply lines of its enemy. But once one side uses such a weapon the other side will feel that it too must engage with its most powerful weapons. Frustration is likely to set in when it appears that restricting such weapons to the immediate battlefield of the war is not sufficient to win. It might then be seen as necessary to destroy the enemy’s airfields and the power centers in its capital with longer range, more powerful nuclear weapons.

Just such a sequence of escalation in the use of nuclear weapons from tactical use in a local battlefield to strategic use in the destruction of an enemy’s cities was shown to be likely in a 1983 simulation described in a recent article by William Langewiesche in The New York Times Magazine. The simulation was large scale and involved much of the U.S. defense establishment. The simulation began with a conventional war between Russia and the West on the fields of Poland and East Germany. As it began to appear that the West was losing and the Netherlands was threatened, the West initiated the use of small tactical nuclear weapons that it fired onto the enemy’s supply lines in the local battlefield. Russia followed suit. Within a few days the airfields behind the frontlines from which the planes dropping the tactical weapons took off were struck with larger nuclear weapons. Finally, strategic weapons were used against the capitals of Western Europe and Russia.

One fears the near inevitability that one or more of the current wars in our world will end in nuclear war, the accompanying nuclear winter, and the possible end of human life on Earth.

The results surprised those who participated in the simulation. The conclusion was that a nuclear war cannot be controlled.

Our world has many local conflicts such as the wars in Ukraine and the Middle East that involve nuclear powers. This is in addition to major geostrategic conflicts between the nuclear powers of U.S., Russia, and China. All of these conflicts have the potential of becoming nuclear.

Russia, for example, has warned the West that it will use a nuclear weapon in its war with Ukraine if it believes it is losing the current war with conventional weapons. Russia is thus telling the west that “we can’t lose.”

Israel has warned that it will exercise “The Samson Option” if it is in a war with its neighbors and believes it can no longer defend Israel with conventional weapons. The Samson Option involves the nuclear bombing of cities such as Damascus, Bagdad, or Cairo with nuclear weapons. More recently, Israel’s Heritage Minister Amichai Eliyahu has raised the possibility of dropping a nuclear bomb on Gaza. Israel too is thus telling the world that “we cannot and will not lose.”

It is likely that the United States too believes that “we cannot lose.” If it is in a war with China using conventional weapons and China is gaining the upper hand then it is quite possible that the U.S., with its triad of nuclear-armed submarines, bombers, and land-based missiles, would use these nuclear weapons. In fact, many in the U.S. defense establishment believe that a nuclear war with China can be fought and won by the U.S. Thus, the U.S. too believes that “we cannot lose.” Similar considerations by the U.S. would apply if it were losing a war with Russia.

Other states with nuclear weapons may also believe they cannot lose. North Korea has stated that it would not use nuclear weapons in a preemptive strike but would use its nuclear weapons if attacked, and recent events on the Korean peninsula suggest that war between the two Koreas is a real possibility. It also seems likely that if Pakistan or India were engaged in a conventional war and one side was losing, that that side would believe they could not lose and would initiate a nuclear exchange.

The likelihood of the use of nuclear weapons becomes still greater if other nations such as Japan, Brazil, Iran, or Saudi Arabia join the nuclear club in the interest of deterrence (no nuclear armed country has ever been invaded) and adopt the meme of “we cannot lose.”

All this makes one pessimistic. One fears the near inevitability that one or more of the current wars in our world will end in nuclear war, the accompanying nuclear winter, and the possible end of human life on Earth.

What can be done? It seems the only solution is the complete abolition of nuclear weapons as proposed in the Treaty on the Prohibition of Nuclear Weapons that has now been signed by 93 non-nuclear states. Unfortunately, the nuclear states have not signed onto this treaty but should be encouraged to do so.

Skeptics will say that nuclear powers might sign on to the Treaty on the Prohibition of Nuclear Weapons but would hold in secret a few nuclear weapons so as to be able to dominate their enemies in a conventional war. That may well happen, but the vast reduction of nuclear weapons that the treaty would require and the absence of nuclear fear it would bring with it would make the universal adoption of the treaty a self-perpetuating step toward the world we deserve and must have.
