Bro why should they have not?? They were defending Islam from the crusaders for a long time and were the strongest force in the world for a long time they had every right to make a claim, the office of Caliph was never reserved for one people. Unless you hold the Shia pov. I know about the Young Turks and how racist they were but you forget Caliph Abdul Hamid ii was a pan islamist and he would have sided with the Arabs in their legitimate demands had the Arabs not forced his hands by join Britain/France in their war against the Ottomans.
I am just telling you that it worked both ways. It were the cousins of the Turks (Mongols) who destroyed Baghdad and ended the Golden Age of Islam.
I am not convinved at all. Read more about the Ottomans and their un-Islamic practices. Read about how "Caliphs" treated their brothers or others who threatened their succession to the throne. You will not believe it. Also how could they be both Caliphs and Sultans at the same time?
I know that you said that you lived in Turkey and liked it but that should not impact on your judgement. I like Turks as well - as long as they are of the Sunni kind since the other is constantly conspiring against the Muslim world.
The Arab Caliphs, who conquered all the known current Islamic world, aside from tiny Balkan and Anatolia that the Turks conquered, never called themselves anything other than Caliphs.
Look the reality is that the Turks did not want the Caliphate. Why would a person like Ataturk come to power then? And be such a popular figure? More than any Turkish Caliph before (all the Caliphs where half-breeds anyway if you look at their ancestry).
Those demands should have been given to the Arabs of Syria, Iraq and North Africa long before that. It should not even have been a issue.
The Caliphate should be based in the Arab world anyway, preferably Makkah, Madinah or Al-Quds - the most holy cities. Which ethnic group is less important.
I am not a Shia. Far from it. On the contrary I am labelled as a anti-Shia by some users here.
The fact is that there will be no Caliph as of today as the time is not ready. My suggestion seems as a good alternative until a Caliphate can materialize.
