There is no point in discussing something what can't be done. It can only bring more grief. Ottomans didn't impose Turkish language for simple reasons. , at the time todays form of nationalism was unknown. Ottomans ruled mostly by religious discrete, which gave them the legitimacy.
In any case , that happened a long ago, no point asking yourself those questions now??!!!
Not even much point of talking Islamists that and this, it is the time to make some sort of consensus, if you can.
Besides, I know for at least 30 years that Wahabism is extreme form of tribal nationalism.
It is easier to motivate someone who is not a Turk to fight for Turkiye if you give him Islamist card
I , myself am Nationalist but I am not secularist. For simple reasons, I can't relate to todays fraud. Praying on the streets etc.
It is not the time now to be desperate or angry or " what if" , the time is for something else.
One more danger, where Islamism , correctly managed, can be useful is to counter what happened to Korea and Japan.
After years of teaching their kids " wisdom" of Talmud and waving Israeli flags , now Japan is going to get 100s of thousands of immigrants from India and Africa but not from Cambodia.
That's what happens, when the Western line of thought is allowed in the country.
By this I am criticising Indians or Africans , it just shows what happens.
War is coming, whether you like it or not, so let's try to find consensus and get together as much as possible.
