In order to get the specified spoils, do you need to own all of the countries listed?
For example, over the map I see :
My Spoils ([bracketed] if owned, next set worth 30 troops): Spoils[Cairo] Spoils Vancouver Spoils Stockholm Spoils [Delhi] Spoils [Port Moresby] . Where the brackets indicate which I own.
Does it mean I must control all of these countries to earn the 30 troops?
