The deal does not say that they give you 30% or 80% or 150% land immediately out of war! It just says they will give! They can give it end of age as well!
Also the deal states to give the land for number 1 vs number 2 war and when CR has bowed out of the race, CR has actually deal broken WSK. As WSK is still in the race to win. So CR should be the ones giving the acres to WSK so they can go and fight vs number 1 i.e. Emeriti!
