I think Federalism is for a big county like Ottoman or RussiaFederalism has not helped germany or the US to diversify economical development through every part of the country. Old east germany is still behind western parts and most box shape bordered american states are worthless sandbags to overall US economy.
The concept itself is a bit idyllic to begin with. Turkey has tried, very hard in fact, with the South Eastern Anatolia Project, billions down the drain with nothing to show for it.
Nevermind the fact that federalism is such a sore spot for Turkey with its separatist movements that it would immediately lead to a war. We already had a kurdish separatist party use government municipalities to aid themselves in the war effort in easten cities.
Turkey himself is a only a state of an never-existed Ottoman commonwealth or the future Turkic commonwealth
Just like England in British commonwealth.We cant divide TC himself.
German was a group of many small kingdoms.That s different.
