Yes sounds like it.
I have to refresh my memory of history, but recall the Ottoman Empire ended after World War I, and Turkey occupies only a small portion of former Ottoman lands.
Erdogan rather obviously wants to get the old Sunni-dominant Ottoman band back together.
Think of Ottoman Turkey and the Austria-Hungary empire as meeting similar fates of shrinkage and dismemberment in the wake of World War I.
It went down along the west coast of the Arabian Peninsula and included Libya until Italy beat them in a war in 1912.
And if you look back hundreds of years yes Ukraine was part of the Ottoman Empire.
