I’m not sure how the new neutrals work, the british allies in a game of AA stay neutral until a specific event? Hitorically the only ally that sat back during the first part of WWII was the United States……From wiki:
The United Kingdom and other independent members of the British Commonwealth, known as the Dominions, declared war on Germany separately, either on the same day, or soon afterwards; these countries were Canada, Australia, New Zealand and South Africa. However, Newfoundland had given up self-rule and was at the time under effective rule from the UK; it did not become part of Canada until 1949. Southern Rhodesia, while self-governing, did not have independence in foreign policy or military matters.
Following the Statute of Westminster in 1931, the Dominions of the British Commonwealth had independence in foreign policy. Australia and New Zealand accepted and reiterated the British declaration of war on Germany. The South African Prime Minister, Barry Hertzog, refused to declare war, leading to the collapse of his coalition government on 6 September; the new Prime Minister, Jan Smuts, declared war that same day. Canada declared war on Germany on 10 September; this was necessary as Canada had ratified the Statute.
The Indian Empire (including the areas and peoples covered by the later Republic of India, Bangladesh and Pakistan) and territories controlled by the Colonial Office, namely the Crown Colonies, were controlled politically by the UK and therefore also entered hostilities with Britain’s declaration of war. The Indian Empire contributed about 2,500,000 personnel. It suffered 1,500,000 civilian casualties (more than the United Kingdom), mainly from the Bengal famine of 1943 caused by the fall of Burma to the Japanese,[15] and 87,000 military casualties (more than any Commonwealth country but fewer than the United Kingdom). The UK suffered 382,000 military casualties.
