Tsingtao 1939: WWII but in January & against Japan - P3 Introduction to Patreon Video 4

The alternate-history case for the United States joining Britain and its allies against Japan rests on Pacific power politics and mounting attacks on neutral shipping.

The sinking of the SS Saint Vincent de Paul, HMS Birmingham's retaliation, and the loss of Akagi turn a local Tsingtao crisis into a South China Sea war.

British, Dominion, Indian, Burmese, French, and Dutch resources give the anti-Japanese coalition far more reach than a Royal Navy force acting alone.

The Panay incident, continuing American exports to Japan, and Roosevelt's loans to the Chinese Nationalists reveal the contradictory US position before the crisis.

A concentrated US fleet near the Panama Canal could move to Pearl Harbor as a forward presence, arriving unusually ready for a Pacific crisis.

An oil cutoff and another Japanese attack on a foreign gunboat could give Roosevelt a political trigger for war, while public outrage and trade interests broaden the case for intervention.

The small Asiatic Fleet has only a handful of surface warships, but its Philippine-based PBY Catalinas provide long-range reconnaissance and limited attack capability.

A brief aside on Admirals Henderson and Blackwood considers how the loss or survival of experienced officers could shape the Royal Navy, especially its destroyer force.

The proposed coalition needs a commander acceptable to British, American, French, Dutch, and Soviet interests, making Roger Keyes the preferred compromise.

The coalition must decide whether to assemble at Singapore or operate from the exposed Philippines, while both sides spend months building forces for a decisive battle.

Japanese forces in China face a difficult choice: reinforce southern operations or retain reserves against Soviet pressure and Allied attacks on sea supply.

In this branch, Soviet help against Japan offers Moscow military leverage and a chance to recast itself as a necessary partner to Western powers.

The proposed Allied fleet would probably form at Singapore, combining American and Royal Navy capital ships, carriers, cruisers, and escorts into a force Japan would struggle to match.

Basing headquarters in American territory, assigning American staff officers, and giving MacArthur an invasion-planning role offer ways to balance coalition command politics.

Submarines, scout aircraft, and light cruisers would find and shadow Japanese movements before carrier aircraft slow the enemy for a battleship action.

A defeated Japanese fleet would be followed by blockade, carrier raids, and occasional bombardment, not an immediate strategic-bombing campaign.

Even with a Tsushima-scale defeat looming, Japanese naval doctrine, institutional rivalry, and the need to preserve face could push the fleet into a decisive action.

American entry strengthens the anti-Japanese coalition but also warns Germany and Italy that attacking any member could turn a regional war into a wider alliance war.
