Would there be a longer Pax Britannica?

Potentially, if Britain avoids or reduces the four major shocks of two world wars, the Depression, and the abrupt end of Lend-Lease, but the result remains uncertain.

Four shocks drove Britain's rapid relative decline: World War I, the Depression, World War II, and the sudden American termination of Lend-Lease. Their cumulative effect matters, so avoiding or reducing one shock does not automatically erase the others. Altering the first war could soften that sequence, but later economic and geopolitical events remain decisive. Britain and the United States would continue negotiating regardless, so a stronger Britain does not imply an unchanged nineteenth-century order.
