I actually invite the Ukraine attack now. It costs Russia more in the long run then Germany, I think. I used to bid units there to make it too costly to attack and keep my fighter. But I don’t anymore.
Anyway, if you invade Norway on UK 1 with BB, DD, AC, 2 TRN, 2 FIG Germany can, and i think should, attack with 2 SS, DD, TRN, 4 FIG, BMB.
According to Frood you wipe out the British fleet with a bomber, fighter left. Replacing fighters for Germany is much easier then for England and you have, in essence, just eliminated England as a threat to the Germans for multiple rounds.
Why? Because they have to protect transports with something! That means buying a capitol ship, replacing fighters, and replacing transports. Germany has to replace 3 fighters, which they can do at a rate of one a round or faster if they want too. Meanwhile, the west can be protected half has hard since it is only America the Germans really need to worry about. Maybe if England stays with the American navy they can cut costs, but even still, that means they can only invade from the north, leaving the south and Africa open for the Axis to leave lightly garrisoned.
