I think it is a good short game but the premise is not correct. It should be: "Will Oceania be able to avoid a global nuclear war until it can come out on top ?" and not "Will Oceania be able to avoid a global nuclear war and come out on top ?"
Reason for this is that the war is unavoidable, so the only way to "win" as Oceania is to is to get your country on white levels.
