The Middle East is in peace, but at a major, massive cost.
The entirety of Jordan and massive chunks of Syria and Lebanon were ethnically cleansed by Israel and Turkey. North Morroco, Western Egypt cleansed too. Arab identity destroyed almost to the extent of pre Colombian American identity. To make things worse, the victims of these campaigns, get no sympathy and are portrayed as collectively responsible for Pan Arab and Islamist dictatorships by the western public. What is left of Syria (and OTL Iraq Anbar) is basically a giant Gaza that gets carpet bombed by Turkey every few years.
As someone who has strong roots to Libya, while I am glad not every Libyan died, I would not want to live in a world were Libyan culture is all but completely extinct!
I do understand your logic though, given the state of the region OTL, but imo it more shows that the OTL MENA is really gone south as opposed to having the MENA TTL be any sort of haven…
I think the appropriate term is "The Peace of the Dead".
I'm not honestly sure what area where most of the people would consider itself Arab today is in the best shape. Oman?
The Epilogue said that the Arab Federation (Britain's old Gulf colonies + Oman) are the only state in the region left that's an explicitly Arab state.
I am in agreement. This is a TL that has been shaped in the image of the egomaniac dictator, Benito Mussolini (it's in the title after all). That world was bound to have great downsides.
But TTL Benito could easily say this to OTL America.
"You Americans speak about liberty and strength, but you fail against puny nations! You fail in Afghanistan! You fail in Vietnam! You fail in Iraq! You fail in China! I have brought balance and piece to the world, while you spread your so-called piece and fail everywhere you go!"
I'm not trying to justify Benito. Despite, as a Jew, wanting to give him a high five, he is still a nasty human being.
But America is a nation that OTL often brings wars to countries, but fails to bring any lasting peace, because we are a nation that only half-heartedly pursues international conflict, and we are a nation that doesn't have to give a shit about the outside world because of two oceans .
Americans can claim to stand for liberty, but because we hold back, we fail to export our supposedly way of life.
Is Benito's actions OK? Not at all.
But is he more effective at state-building? Yes he is.
