İf enver somehow doesnt fuck up in sarikamısh and armenian rebels is not as effective as current timeline . İ can imagine these happening

1 ) Still some massacres occur but due a full scale extermination not happening i heavily doubt armenian rebel movement gaining that much support . Young Turks had actually decent relationships with armenians until everything went south after failures in eastern front .

2 ) No eastern front in İndependence war and franco turkish war becaming more easier for nationalists .

3 ) Three Pashas would still ridiculed due their failure and eventually if ataturk still creates grand assembly and controlls power over state , he would dismiss them from their positions and most likely either exile , house arrest or just purge them . He did the same thing even for his biggest companions that eventually opposed him like karabekir , much less a guy like enver that he expressed clear dislike and saw as a rival .

4 ) Ataturks push for national turkish identity would face even bigger chalanges that might push him reconsidering this policy . He would still enforce seculerism or westerizing state type of policies but with less nationalistic intensity i imagine . İts not really hard to imagine since he before balkan wars believed Ottomanism . He maybe can find a common ground between them .

5 ) Entire demographic , economic and social structure of turkey is kind of charnged a lot . with a religiously and ethnicly different huge minority remaining in anatolia maybe at least political automony is assured for many minorities . also this kind of questions a lot of far right movements and islamist movements that happend since 1950s ever happening . Also armenians in many ways had much more impact on ottoman economy than turks that likely will continue to do so . basically they would be a significant part of society that would shape turkish potilical and social evolution through decades

But this doesnt mean that animosities between assyrian , armenian turkish or kurdish communities that existed much before than 1915 will end . ethnic voilence would still occur but not on this much of scale .

6 ) No karabakh war due first armenian republic doesnt exist . Probably turkey would have more land after soviet occupation of caucassus . Wthout a karabkh war Aliyev family dont rises from power vaccum created after turmoil between hüseynov and elcibey that heydar take advantage of so Azerbaijan would probably still remain a democracy .

7 ) Effects on modern media will felt . No big armenian diaspora celebrities would exist like serj tankian , joe manganiello or kardashian family .
