Portugal /Spain: Frawley Method
Asc = Capricorn = Portugal (My favorite), ruler = Saturn (06°43´Capricorn (Rx)
Desc = Cancer = Spain, ruler = Moon = 21°42´Cancer.
As the moon is the ruler of cancer, according to Frawley, the moon can not be the ruler of house 7 because it governs the flow of events, however, we must take the dispositor of the moon, but as the moon is in cancer she is your dispositor. Then the Moon is the ruler of the house 7.
Mars conjuction south node (mars ruler house 10) a bit bad for Portugal.
Moon house 7 same sign that desc, a bit good for spain.
Moon trine antiscia fortune (fortuna = 23°57´Scorpio, house 10), good for spain.
win spain.
