Yea but even from France, it still forces the German bomber to land in Africa if you hit the southern Atlantic. We talking of shuffling troops trough Sea zone 22 and 23 here.
This means German cannot even land in Moroco Algeria or Egypt if operating from France. The only way to hit that US transport from France is to land in central Africa. That scenario is not likely to happen since you are shuffling troops in central Africa.
From game experience, that US transport is pretty much safe unless German Bomber is based in Egypt ( Or Algeria but I don’t see a German Bomber live long there ). If the German bomber happens to be in Egypt ( or Algeria ), well, the transport can rejoin the main fleet in one turn at Gibraltar sea zone 12 to drop in Algeria ( killing it if it’s there). Or simply go in Pacific if it’s needed there.
Also, at worst, you still can pop in Brazil whatever you need to protect it from a lone bomber if you really want to keep at it. In short, it’s too far for Germany to really be able to do anything worthwhile to prevent you from landing in Africa. Yet, 1 tank, 1 infantry per turn will make sure you hold Africa as long you sink German Transport with UK bomber if they went for Egypt G1.
