If France held out in 1940, would Britain supply Japan with fuel to discourage an attack on the Dutch East Indies?
Short answerPossibly, but it would depend on British interests and how much Britain relied on American supplies.
NotesIf France remained in the war, British fuel deliveries are proposed as a way to discourage Japan from advancing toward the Dutch East Indies. Whether Britain would choose that course depends on its interests under the changed circumstances. Reliance on American factories for aircraft and other supplies could affect the calculation. The hypothetical therefore does not establish an automatic British decision to supply Japan.
