Didn't you have some smart comment about battles in space and battles in time a while back (I might be mangling the concepts here - mind's a little rusty). Definitely, time is not on your side in Spain. Sure, overall you're bigger and better, but to get those forces and get them to Spain (and without denuding your frontiers) is going to be tricky. Now imagine if the Brits do a Wellington and land expeditionary forces in Spain... Nah, they're not that good.
It'll be very interesting to watch: this is the first time you really have to respond to events, rather than setting the pace yourself (Turkey's surpise entrance into the war didn't count).
Let's see how well you improvise.
