Ok I have a new idea for how to (possibly) slow this tactic down.
UK1 Build 3 bomb (36) 1 trans (or other unit or save).
UK2 Destroy med fleet with 4 bomb, and 1 fig, landing in Egypt or Caucasus. Have Egypt forces push forward.
With any luck if UK builds up some extra fleet on UK2 the US may be able to drop 1 trans in France on there second turn, followed by major invasions UK3/US3. I’d probably go for an AC or two if needed(using US fighters if you lost any) plus a cruiser or two if the funds are available.
Also, with the remaining bombers, plus the US bombers you can reduce Italy to one inf per turn and begin picking on Germany.
At some point, probably turn 5 you should take Italy from France unless Germany begins coming after you, and even then you should be able to overpower Germany at some point.
