Kind of building off whats been said, in regards to other nations getting involved in the SCW, I think the UK and France and maybe even Portugal should get options to send weapons or an expeditionary force or a full blown intervention as well as the SU, Germany and Italy. You could see Mussolini with his stupidity (maybe not the best word but you know what i mean) thinking to himself "Ha now is time to seize the Balearic's or Spanish colony's" or even Britain or France if they are feeling crafty enough (maybe in return for helping the republicans?) and imagine how inflammatory it would be if French and German troops were exchanging fire and Air forces dog fighting in Spain and how quickly that could escalate into that being on the true German-French border. Basically what I'm saying is I hope that the SCW is more dynamic than in previous HOI games where its normally as the original poster said something you just watch out the corner of your eye.
