Your logic is fallacy because you do not need to send more troops to Africa. If you prevent UK reinforcements from arriving by disrupting supplies, then there is no need for extra troops.
We already know the effects of this because
1. USA did it against Japan
2. UK did it against Italian/German reinforcements/supplies in Med.
We know the strategy works, we know the effects the lack of supplies does to troops and morale. There is no reason to NEED to dedicate more troops to Africa.
Even if somehow they get reinforcements/troops, this now means they need more ammo, more fuel, more food, to supply the troops. The more you cut the supplies, the more pressure it puts on the UK.
Ugh. Why have ANY troops there at all? I'm not talking about sending MORE troops I'm saying ignore the joint. Use everything for SU.
Look the thread title says this:
"Will North Africa be as Important in the Game as Historically?"
First off that is a fallacy because history proved it wasn't important. It was only PERCEIVED to be important. Big difference. A perception without hindsight is valid. A perception when you know the future is not.
This was why in HOI1, HOI2 and HOI3 NA was basically ignored. The OP and others thought putting resources there would make it matter. And in one concept they are right. You need to change reality in the game to make it matter because using hindsight and reality NA just doesn't matter.
