What if US listening devices were discovered in the Japanese delegation's rooms at the Washington conference?
Short answerThe scandal could collapse the conference, restart British capital-ship construction, and politically weaken the US building program.
NotesJapanese delegates already suspected that their discussions were being monitored, but proof would turn suspicion into a major diplomatic scandal. The Washington conference could collapse under the resulting political pressure. Britain might then complete the G3 battlecruisers and begin the N3 battleships. In the United States, exposure of the operation could strengthen isolationist opposition and undermine appropriations for the American building program.
