A military strategist argues that developing missiles accurate enough to destroy all enemy nuclear weapons in a surprise first strike would maximize national security. Why would deterrence theorists argue this actually increases the risk of nuclear war?
AEnemy submarines would automatically launch upon detecting the first strike, making preemption self-defeating
BIf the enemy believes their second-strike capability is threatened, they face a 'use it or lose it' dilemma — launch before their weapons are destroyed — shifting toward launch-on-warning postures that make any crisis more likely to escalate
CArms control treaties carry automatic war-declaration penalties for first-strike capability development
DEnemy leaders would interpret the capability as purely defensive and accelerate their own first-strike buildup
This is the central paradox of nuclear strategy. Deterrence rests on second-strike capability — if I can survive your first strike and retaliate, you won't strike. If you develop weapons that can destroy my entire arsenal before I can respond, my deterrent is worthless unless I launch first. This 'use it or lose it' pressure means that any sign of incoming attack, real or false, becomes a trigger for immediate launch. Paradoxically, seeking decisive first-strike advantage can make both sides hair-trigger and war more likely, not less.
Question 2 Multiple Choice
The Cuban Missile Crisis of 1962 is best understood as evidence of which of the following?
AThe Soviet Union was actively planning and preparing a nuclear first strike against the United States
BMAD logic worked exactly as designed, with both rational leaderships making optimal decisions throughout
CDeterrence held partly through luck — multiple near-misses from miscommunication, incomplete information, and individual actors who nearly triggered launches independently of leadership decisions
DThe US and Soviet Union lacked sufficient nuclear weapons to credibly deter each other in 1962
The crisis revealed how fragile deterrence's rationality assumptions were. A Soviet submarine commander nearly launched a nuclear torpedo believing war had already started (he was talked down by Vasili Arkhipov). An American U-2 accidentally violated Soviet airspace at the crisis's peak. ExComm deliberations showed how close to miscalculation both sides came. Deterrence held, but the resolution involved secret concessions, back-channel communication, and a degree of luck that neither side had planned for. This drove subsequent arms control negotiations: both sides recognized the system had nearly failed.
Question 3 True / False
Deterrence stability can be undermined by weapons that improve one side's first-strike accuracy, even if the total number of warheads on both sides remains equal.
TTrue
FFalse
Answer: True
True — this is a key insight of nuclear strategy. A more accurate missile can destroy more of the opponent's land-based arsenal in a surprise strike, threatening their second-strike guarantee. Even without increasing raw warhead counts, improved accuracy can shift the strategic balance by making a disarming first strike feasible. The US-Soviet arms race was not purely about numbers — accuracy, delivery systems, and survivability (submarines, mobile launchers, hardened silos) mattered enormously for whether second-strike capability remained credible.
Question 4 True / False
Nuclear deterrence is self-sustaining: as long as both sides possess nuclear weapons, rational leaders will automatically refrain from nuclear use.
TTrue
FFalse
Answer: False
False — deterrence depends on conditions that are never perfectly met: reliable second-strike capability (weapons must survive a first strike), rational leadership (both sides choose survival over ideology), and accurate information (no miscalculation, no accidental launches). The Cuban Missile Crisis showed how a submarine commander, acting on incomplete information and without contact with Moscow, nearly launched independently. The 1983 Able Archer exercise almost triggered a Soviet launch due to misread signals. Deterrence is a fragile equilibrium, not a physical law, and it has survived partly through luck as well as design.
Question 5 Short Answer
Explain the 'stability paradox' of nuclear strategy: why can building more powerful weapons make a nuclear-armed state less secure rather than more secure?
Think about your answer, then reveal below.
Model answer: Deterrence stability rests on both sides having a secure second-strike capability — the ability to absorb a nuclear first strike and still retaliate devastatingly. If one side develops weapons accurate or numerous enough to destroy the other's nuclear arsenal in a first strike, the threatened side loses its second-strike guarantee. This creates a 'use it or lose it' dilemma: launch before your weapons are destroyed, or risk having no retaliatory capacity. The result is that both sides adopt hair-trigger launch postures, any crisis becomes more escalatory, and the risk of war rises. More destructive capability paradoxically reduces security by threatening the very second-strike stability that keeps deterrence working.
This paradox was the conceptual foundation of SALT negotiations and the ABM Treaty: the US and USSR agreed to limit certain weapons — including missile defenses — because improving first-strike capability or eliminating the other side's second-strike guarantee was understood to be destabilizing. The strange logic of MAD is that vulnerability is stability.
