@allboxcars:
Does it have to be in writing?
Or done as a grand speech mimicking the leader of the power you are playing.
"We stretch out the long arm of brotherhood and motherhood to the Australian and New Zealand people, and to the Indian people, whose army has already been fighting with so much distinction in the Mediterranean theatre. This movement of our naval forces, in conjunction with the United States main Fleet, may give practical proof to all who have eyes to see that the forces of freedom and democracy have not by any means reached the limit of their power.
I must admit that, having voted for the Japanese Alliance nearly 40 years ago-in 1902-and having always done my very best to promote good relations with the island Empire of Japan, and always having been a sentimental well-wisher of Japan and an admirer of her many gifts and qualities, I would view with keen sorrow the opening of a conflict between Japan and the English-speaking world.
The United States’ time-honoured interests in the Far East are well known. They are doing their utmost to find a way of preserving peace in the Pacific. We do not know whether their efforts will be successful, but if they fail, I take this occasion to say-and it is my duty to say-that should the United States become involved in war with Japan the British declaration will follow within the hour."
