@The-Janus indeed hurting the luftwaffe is a plus but not if it costs you way too much. Keeping your fighters with UK and alive in the Med then they can go to moscow fast.
Of course it can. It makes no difference that originally it was a neutral territory. Its current status is a territory of the United States and therefore, with an IPC value of two,it can be a location where a minor industrial complex can be placed.
@The-General-0 A quick US liberation of London assumes the German navy and its transports have been eliminated.Italy can throw a wrench into the allies plans as well.
