The premise here is that immediately after the allies land at Casablanca in Nov '42 (Operation Torch) Franco sees the writing on the wall and decides to position himself firmly in the allied camp with a DOW on Germany.
The goal is to expel the axis from North Africa, secure it as expanded colonial possessions and keep it in any post-war negotiation.
IOTL, when Hitler invaded Vichy France, Franco ordered a partial mobilization as a precaution, bringing the total Spanish Army troop number to 750,000 men, along with (+/-) 20,000 airmen and (+/-) 30,000 sailors.
This coupled with the fact in a general war scenario and even larger force could be mobilized, do you think Franco could have successfully seized North Africa under the auspicious of Operation Torch and likewise been able to keep it in post war negotiations?
Bonus Points: If you describe how
Depending on your answer, how would Franco's gambit effect WW2 in general?
