-Option A for Egypt.
All the ingredients are there for them to make it out fine, from food production to local industry up to and including domestic natural gas production.
And they border Israel to boot, which is not a place Alexander wants them making common cause with. Bribes, not threats.
Furthermore, Egypt serves as a counterweight to Iranian and Turkish influence in the Med and Middle East.
They cant bind Egypt into the Russosphere without risking internal instability and fucking over Suez access.
I suspect Russia isnt popular among the common Arab after the invasion of the Middle East, especially since Egypt would have been a destination for refugees, and lacks the soft cultural power the United States used to wield.
-Sudan is in Egypt's economic orbit, or so I hear. So where Egypt goes, it goes in some degree.
-IMO, Ethiopia survives fine as a counterweight for Egypt.
Its centrifrugal tendencies are mediated by a government for which the Ethiopian Civil War's 1.4 million dead is fresh in memory; literally ended in 1991, well within living memory. Drought is a potential problem, though.
-Libya is fucked. Lots of oil and natural gas, very little water, plenty food imports.
Its caught in a tug of war between the Turks and the Egyptians, something that suits Alexander just fine as a diversion of their energies.
Plus, its a convenient staging point for Russian shenanigans into Italy. Which brings EU attention.
-Eritrea is fucked.
The authoritarian assholes who took over after the Ethiopian Civil War have been systematically running the place into the ground, and Alexander does not do charity. Nor does he have to if he literally has naval basing in Yemen and land forces in Saudi Arabia. Expect him to ignore them
-Algeria is a historically Russian ally and arms importer. And a significant oil and gas exporter.
They should do fine.
-Morocco is politically stable, partly controls the only other exit to the Med with Spain, and holds 75% of the world's phosphate reserves.
You know who'd be annoyed at instability there? Everyone, but especially Russia's allies in India and her population of a billion plus hungry mouths as well as Japan. Plus, as the EU recovers, Spain is on the other side of the Med, and any overt action has to reckon with that.
I expect them to do mostly fine there, regardless of what happens with Western Sahara.
-Tunisia is politically stable, and does not hold anything people particularly want from them.
They both export and import food. But a chunk of its economy is dependent on tourism.
They're gonna take a beating for a couple decades, but I dont expect that to go further than that.
-Western Sahara has been illegally occupied by Morocco for over fifty years now. Population isnt huge; maybe 600k in 266,000 sq km.
Illegally occupied according to the UN General Assembly, and most of Africa. The Polisario Front have Algerian support and diplomatic recognition from 46 countries, and was extended membership in the African Union.
With tacit US and French support for Morocco gone, and if the Algerians have Russian support, there are good odds it becomes independent and a de facto Algerian client state. One way or the other.
Especially because Western Sahara does have significant phosphate reserves of its own.
