You haven't got an answer because there isn't an answer to give... the best we can do is throw up a list of tracks we know that were made for the album, and since I'm bored.. I'll do just that.
One Nation:
Tattoo Tears
One Nation
Let's Fight
How Many Shots Will it Take?
Brothaz at Armz
Millitary Minds
Thug Nigga
U Don't Have To Worry
Worldwide Dime Piece (AKA Bitches, AKA Cali Pussy)
My Own Style (at 1:28 mentions visualising one nation, and at the end of the track ad libs in the background about East & west plus with greg nyce on the track, it seems to fit in with the general time frame of the other tracks since pac was working with greg nyce alot for this project)
I also have some theory's on 4-5 other tracks belonging to the project, but since they're unconfirmed I'll stick with what I know...
