I agree with everything Nagano just said based on my own experience.
I would add, however, that the Taranto raid combined with support from the Indian navy and air force makes advancing in Africa a much harder prospect. If Britain does this combined with a US KIF strategy, I don’t think Italy has a chance of making it past Egypt no matter what Germany does. When I play the Allies, this is my strategy of choice.
Yes, the allies can do that, but then japan is unchecked
Honestly imo in the global game Japan is a lot less of a threat then Germany because America can always come back and crush them later on.
