Not an authoritative source, due to it being merely a Quora question, but the title alone gives ppl something to ponder about:

Turkey has 14 neighbours, including immediate-sea-zone ones, and is only friends with 4 of them- Israel, Ukraine, Georgia and Iran.
Turkey's arch enemies:
1)Amernia- for the infamous
https://en.m.wikipedia.org/wiki/Armenian_Genocide
2)Greece- long lasting hostility by the legacy of Ottoman occupation. Fought multiple wars with each other.
3)Bulgaria- long lasting hostility by the legacy of Ottoman occupation. Bulgarian history is described as 'the Dark Ages' during that period.
4)Romania- long lasting hostility by the legacy of Ottoman occupation.
5)Russia- Geopolitical arch rival for dominance and influence in the Black sea and is a backer of Slavic Balkans. An Underlying theological rivalry as well due to Constantinople aka Konstantinoyye aka Istanbul.
6)Cyprus- instigator and backer of the formation of Northern Cyprus.
All six are Christian nations. 4 of them in EU and are hence - 'the West'(which Turkey is dying to enter)
Hostile nations:
1)Iraq- Turkey violated Iraq's borders multiple times. Turkey even enacted a law for permission to be given to Turkish troops to cross the border into Iraq as when it pleases.
2)Syria- ongoing Syrian war. Violated Syrias border mutiple times, even sending troops to a tomb in Syria. Syria's Hatay annexation by Turkey.
3)Egypt- mutiple diplomatic crisis-es.Egypt even expelled the Turkish ambassador and recognised the Armenian Genocide.
Unfriendly nations:
1)Lebanon- inaction of Turkey towards Israel, not to mention Turkey and the Israel are even friends.
All 4 above are Muslim states. Even Muslims are angry with their Muslim brother, Turkey.
Friendly nations:
1)Ukraine- simply because both hated the Russians. Relations of convenience.
2)Georgia- again, both hated the Russians. Yet another relations of convenience.
3)Iran. The only true friendly neighbouring state.
4)Israel- together in bed only because of Israeli antagonism with Syria and Iraq.
2 of them Christian states, 1 of them Muslim and one Jewish.
All these are not to mention the fifth column in her midst, the Kurds. Turkey can lose 1/4 of her territory at anytime.
Our Turkish friends prefer voicing out their opinion about Xinjiang across the steppes than to be focused on their 'Kurdish Problem' in their own house.
So the Chinese are hated by both East and West, while the Turks are well-liked by everyone in her neighbourhood, including fellow Muslims.
LoL.
Thanks.
