I just want to say that this in itself is strange, what is now in the game. Look at Finland, in the photo. She declared independence in the outback, and is now there. Yes, increasing the number of troops would help Finland free all of its national territories, but AI itself is stupid and will capture all surrounding provinces, not just national ones. In the event that the whole territory of Finland declared independence, without a huge number of troops, this would lead to the same result as your version, only in a more realistic way.
