The UK tends to just hand over Cyprus to Greece, so the only worry would be the Ottomans. Our army is stronger than theirs, so if they don't have allies it shouldn't be exceedingly difficult, just need to build enough transport ships to send our troops there.
There's an event later on where the great powers decide if they should keep the Ottoman empire strong or force them to make the Balkans independent, Greece tends to be made whole after that.
Allies: Ottomans are an option. Spain would probably still be a great power if it hadn't been for the prestige hit they took for going through a revolution. Their army is a lot stronger than ours. If we "sphered" them, influenced them to the point that they basically do whatever we tell them,, they'd be a decent ally, but there's a lot of competition for influence in Spain. To fight Prussia France has to let them through their country.
Speaking of Prussia, the
real schleswig war is just 3 years away. In our timeline it might take longer to happen. A French-Prussian conflict and an Austrian-Prussian conflict are inevitable. Depending on which happens first, how should we react?
Colonies: Where would you like to get some? We could take Sinai from Egypt/Panama from Colombia to form the Suez/Panama canal later. We could backstab Persia, or go for East/West/North Africa, or Afghanistan and pre-Pakistan. Since our population is small we need a strong navy to remain in power. We could just take a small strip of coastline for naval bases or form a big chunk of a colony for resource exploitation. After 1870 you can just grab as much of Africa as you want, by the way, with no consequences.
Sphere of Influence: Should we try to obtain more Italian minor states or try for somewhere else? Sphering is nice when you want to have access to the resources of a country but conquering them would be too much of a hassle. The only one that's really not a good idea to sphere is China.
