So Daniel in WWW had to take over Romania for the oil, basically because he really needed the oil and Romania would not join the Axis. Historically Romania obviously went Axis and was the main supplier of Axis oil. So lets say Daniel or myself when I play Germany get Romania to become an Axis ally. Will I get some of that sweet oil without having to trade for it? or will I still have to trade for it giving up precious factories? If I still have to trade for it why wouldn't I just do what Daniel did and take it over forcefully.
