Attack on Pearl Harbor

Background

Quigley locates the immediate origins of the Japanese attack in the deteriorating economic confrontation between Tokyo and Washington from 1937 onward. Japanese expansion into China after the Marco Polo Bridge incident (July 1937) and the formal Tripartite Pact with Germany and Italy (September 1940) produced escalating American economic countermeasures: the abrogation of the U.S.–Japan Commercial Treaty (1939), the embargo on aviation fuel and scrap iron (1940), and the freezing of Japanese assets and the de facto oil embargo (July 1941) (T&H 580–595).

The oil embargo was, in Quigley's reading, the strategic detonator. Japan imported approximately 80% of its oil from the United States; the embargo gave Tokyo a finite stockpile and forced a strategic choice: withdraw from China (politically impossible for the Imperial Army faction in the Cabinet) or seize the oil resources of the Dutch East Indies (politically necessary, but strategically meaningful only if the U.S. Pacific Fleet could be neutralized). 'They decided to attack the United States first. From this decision came the Japanese attack on Pearl Harbor on December 7, 1941' (T&H 583).

The operational design — a carrier-based strike against the fleet at anchor in Hawaii — was Admiral Yamamoto's. The diplomatic cover, the so-called Hull–Nomura negotiations in Washington, continued in parallel almost to the moment of attack; the Japanese declaration of war was, by accident or design, delivered after the bombs had begun to fall.

The attack

Two waves of Japanese aircraft from six carriers struck Pearl Harbor between 0755 and 0945 Hawaii time on Sunday 7 December 1941. Four battleships were sunk (Arizona, Oklahoma, West Virginia, California) and four damaged; three light cruisers, three destroyers, and various auxiliaries were damaged or sunk; 188 American aircraft were destroyed, predominantly on the ground; approximately 2,400 American servicemen were killed and 1,200 wounded. Japanese losses were 29 aircraft, 5 midget submarines, and 64 men (T&H 583).

Quigley emphasizes a critical operational detail: the three American aircraft carriers in the Pacific Fleet — Enterprise, Lexington, and Saratoga — were at sea or in California, and were not hit. This proved, by 1942, to be the decisive omission. The attack disabled the battleship-centric fleet that would have lost the war against Japanese sea power in 1942; it did not disable the carrier-centric fleet that won the war at Midway (June 1942) and after. The attack's most lasting strategic effect was thus to force the U.S. Navy to fight the war it could win rather than the war it would have preferred to fight (T&H 678).

Quigley's broader weapons-systems analysis in Weapons Systems and Political Stability situates Pearl Harbor in the transition from battleship to aircraft-carrier dominance: 'A related idea assumed that the area in which a fleet could function effectively was limited by the positions of its major bases, such as Pearl Harbor, Gibraltar, Singapore, Toulon, or Kiel' — a doctrine the war was about to invalidate (T&H 678; Quigley, 'Weapons Systems,' 1960).

Quigley's framing

Quigley's reading of the attack is unsensational and structural. He does not entertain the 'back door to war' thesis (that Roosevelt had advance knowledge of the attack and allowed it to occur to bring the U.S. into the war), but he is also clear that the American oil embargo was a deliberate provocation designed to force a Japanese choice and that Washington was substantively prepared for war by autumn 1941, with the precise form and timing of the Japanese response being the only open question (T&H 580–595).

The deeper Quigleyan reading is that Pearl Harbor exposed the catastrophic Japanese miscalculation of American resolve. Japan had to assume — for the attack to make strategic sense — that a single devastating blow would convince the United States to accept a negotiated Pacific settlement leaving Japan in possession of its East Asian gains. This was, in Quigley's words, 'an inescapable decision' produced by the Imperial cabinet's specific assumptions about American character and political will (T&H 583). It was exactly wrong. The attack converted American public opinion from divided to unanimous within hours and made unconditional surrender — the war aim the Allies announced at Casablanca in January 1943 — politically possible.

From the Second World War's global geometry, Pearl Harbor was the moment the two theaters merged. Hitler's gratuitous declaration of war on the United States four days later (11 December 1941) — a decision Quigley does not analyze at length but which he treats as Hitler's second great strategic error of 1941, after the invasion of the USSR — completed the strategic situation that doomed the Axis: a single coalition fighting on every front, with American industrial capacity available to both the Atlantic and Pacific theaters.

Outcomes

The immediate outcomes were political. The U.S. Congress declared war on Japan on 8 December (1 dissenting vote, that of Jeannette Rankin). Germany and Italy declared war on the United States on 11 December; Congress reciprocated the same day. The Atlantic Charter agreements that Roosevelt and Churchill had reached at Placentia Bay in August 1941, and the Lend-Lease aid program (March 1941), were now converted from undeclared support of Britain into full belligerency.

Operationally, the Pacific war ran a six-month Japanese expansion (Singapore, the Philippines, the Dutch East Indies, Burma) followed by stabilization at the Coral Sea (May 1942) and reversal at Midway (June 1942). The American island-hopping counter-offensive from Guadalcanal (August 1942) onward methodically reduced Japanese territory until the strategic bombing campaign from the Marianas (1944–1945) and the atomic strikes on Hiroshima and Nagasaki (August 1945) produced surrender (T&H 695–720).

Domestically, Pearl Harbor produced the political consensus that allowed Roosevelt to mobilize the American economy at scale and run the war as a unified national project. The America First Committee dissolved within four days of the attack; congressional opposition to the war effort collapsed; the wartime mobilization that Quigley treats throughout Tragedy and Hope as the foundation of the post-war American international position was made politically possible by what happened that Sunday morning in Hawaii.

Legacy

For Quigley, Pearl Harbor's longest-running consequence was the establishment of the United States as a permanent Pacific power. The pre-1941 American posture in the Pacific had been semi-detached — possessions in the Philippines and Hawaii, commercial interests in China, but no commitment to enforcing a particular order. The post-1945 posture was the opposite: bases in Japan, the Philippines, Okinawa, and Korea; security treaties with Japan (1951), the Philippines (1951), South Korea (1953), and Australia/New Zealand (1951); and a Seventh Fleet that has remained the dominant naval force in the western Pacific to the present. Quigley reads this as the structural consequence of the war the attack initiated (T&H 920–940).

The attack also functions in Quigley's analysis as the case study in misdirected strategic action. It is a 'rational' decision by the Japanese cabinet on the assumption that American national psychology was a particular thing; the assumption was wrong; the decision was therefore catastrophic. The lesson — that the most rigorous internal logic cannot rescue a strategic decision built on a false assumption about the adversary's political character — is one Quigley applies repeatedly in the corpus, most notably to Hitler's 1941 invasion of the USSR and to the inter-war Milner Group's assumption that Hitler would be a manageable bulwark against communism (T&H 583; AAE 230–240).
