The thought experiment considers how Britain might respond if Germany escalated to nuclear attack before the Allies had an atomic weapon of their own. Earthquake bombs are ruled out in 1939-40 because they were not yet available. British chemical-war stocks remain a possible retaliatory weapon, with night delivery presented as the likely option. A German nuclear breakthrough would therefore invite devastating escalation rather than provide a stable route to victory.

Britain could answer nuclear escalation with chemical warfare
