R1 arms race = competitive acquisition + advancement of military capability → burden falls on economies and societies → yet weapons stay, because they are believed to buy security → disarmament stalls in that gap R2 the Cold War priced the race: debt, welfare foregone, a collapsed USSR → yet no state surrendered the bomb → obstacle lies in what the bomb is thought to be worth, and in a regime the excluded call unequal

economic damage first → debt + dependency for arms importers → India-Pakistan missile competition → Reagan's renewed nuclear race + SDI (1983), never realised → strain → collapse of the USSR → economy could not match capitalist living standards → social cost = what goes unspent — armaments money withheld from human welfare — world under a "balance of terror" — peak: Cuban Missile Crisis — hinge: Gavin — the race also built a deterrent that prevented direct superpower conflict; Waltz — nuclear weapons kept the Cold War "cold" — that belief is obstacle 1: no state gives up what it thinks keeps it safe → obstacle 2: the regime is itself unequal → Perkovich — India + Pakistan outside NPT, unrecognised as NWS — 1995 indefinite extension read as discriminatory → NWS resistance blocks CTBT + FMCT → 2017 ban treaty: no major nuclear power in it → verification hard → moral pressure fails on Iran / North Korea → China will not scrap its arsenal → Perkovich & Acton — weakened US umbrella → Japan + South Korea towards the bomb

Kissinger — deterrence assumes rational actors → the security defence relied on by every nuclear state is itself unsafe

R1 Simpson — universal + verifiable + non-discriminatory process → cost alone has never disarmed anyone — India's No First Use shows restraint is possible → it spreads only when the excluded accept the order as equal R2 the obstacle is political, not technical → verification can be engineered, equality cannot be faked → India's No First Use as the model → Simpson's three conditions as the way forward
