Spain question

[unmerged(138733)]

Does anyone has any suggestions on how to play Spain(either side) in AOD? I played it in HOI 2 and 3. and it was tedious at times.
Should I join the war early or wait till later in the scenario(1938) to decide whether to join one side or the other?

think about rebuilding... this would be much harder the Italy rebuilding Roman Empire
Go with Fleet-in-Beeing and naval bombers. Axis would be a natural ally for me. Take revenge on brits for Spanish Armada, divide and conquer.
