Could the East Asia Squadron cross the Pacific and seek internment in the United States?
Short answerIt could try, but a Canadian Invincible on the Pacific coast could intercept it, and the choice of suitable American ports would be limited.
NotesA west-coast Canadian Invincible could search for German ships trying to cross the Pacific. San Francisco is the likeliest suggested place to seek internment. Seattle and other northern destinations would bring the ships too close to Vancouver and the Canadian force based nearby.
