Could international pressure force an early peace?

Would international pressure force Britain to accept an early peace with Japan?

Probably not: the United States is likely to support or join Britain, the two powers dominate the diplomatic balance, and the war remains distant from the British home front.

No external coalition appears strong enough to compel a negotiated settlement while Britain and the United States remain aligned. A short peace would become plausible only after Japan's fleet had been annihilated and the terms were being dictated from overwhelming Allied strength, not because a Japanese tactical victory created bargaining leverage. A predominantly naval war without bombing at home would also be easier for Britain to sustain politically, especially if the campaign appeared successful. That leaves little incentive to stop before Japan's fleet and economic capacity have been decisively reduced.
