Would the stronger Anglo-Japanese alliance cause war with America?

Would a stronger Anglo-Japanese alliance lead Britain and the United States into war?

No. Anglo-American cooperation would probably continue alongside political disagreements, without a plausible trigger for war.

A stronger Anglo-Japanese alliance is not expected to cause an Anglo-American war in this counterfactual. Professional cooperation could continue alongside governmental friendship and recurring disputes, with no proposed issue large enough to trigger war. Anglo-American relations might be less close than they became historically during the 1920s and 1930s. The more uncertain relationship is between Britain and Japan, because wartime cooperation could strengthen the alliance while emboldened Japanese activity in the Far East could strain it.
