Did the United States expect the Dominions to abandon their Royal Navy relationships?
Short answerNo. Washington could try to weaken those links, but the Dominions remained trusted naval partners inside the British imperial force structure.
NotesBritain could plausibly entrust major warships to Australia, Canada, New Zealand, South Africa, or India, while the United States was far less willing to arm the Philippines comparably. That contrast suggests that the formal British Empire contained stronger naval trust relationships than America's less formally acknowledged protectorate system.
