I have some objections regarding this:
The real war (at least against the Axis) was over with the capture of Berlin in 1945. By this logic we should have what we'll conquer. No matter if we'll capture it one day before timeline or one year. The course of action you propose can even turn players into the defensive as our faction will gain nothing 6 months before the end date. I can't fully agree with that. We already are hard pressed on many fronts and have enough rules as it is, I don't think we would willingly use flaws in the AI or act "gamey".*Since 1944-1945 is getting nearer, I will introduce a new rule with the aim of removing some potential gamey exploits of VCs:
Any non-Chinese enemy VP will count towards our victory only if it has been taken at least 6 months before the end date (Jan 1946) and was not lost during that period (July-December 1945).
Therefore, it will not be possible to do some invasions e.g. 1 month before the end date and jump in the victory scale.
