Of course, Arthur's ambitions weren't so grand as to forcibly control the rise of South American nations.
However, establishing cooperation with South American nations and importing a large amount of mineral resources and petroleum from South America was inevitably necessary.
Speaking of South America, one cannot fail to mention that in history it was the only sanctuary during World War II.
Apart from Brazil, which had some collusion with Germany during the war, other countries maintained neutrality.
Since the focus of the great powers was on the European Battlefield, South America had quite a favorable development opportunity during this period of World War II.
However, for Arthur and Australasia at present, it wasn't so easy for South America to keep to itself.
Only by plunging South America into the whirlpool of war could Australasia plot for more interests in South America.
