These are not the old victory conditions.
Frankly I am surprised the Axis was formed at all. We know of no powers friendly to the United States, or any unfriendly either. The United States has no idea where we will go with isolation defeated.
The Soviet Union and the United States have no predisposition be allies. We may or may not.
The United States offered a prompt peace to anyone who would enter Finland, and this will be executed. Germany missed an incredible chance to gain a back door to British positions, and a front doorstep to Leningrad. The Soviets would be very foolish to allow an empty Finland to exist next door. Any Soviet action in Finland is driven by this imperative. There is no quid pro quo of an alliance to follow.
However the USA reserves the right to make any diplomatic arrangements it wishes, without consultation with the German Foreign Office. If the USSR, or any other power, enters Finland we will accept an offer of peace from them, or will offer peace if they do not. We would have done the same for Germany, Italy or Japan.
The USA engineered a situation in Finland where we believed isolationism would be breeched. This was our intention and the nation which entered Finland only a tool.
In another "world" FDR might have put incredible pressure on Japan with sanctions and embargoes, leading to an attack. In this world FDR decided to put the pressure point in Finland.
