One of the foundational elements of the Lausanne Treaty back in 1923, was the demilitarization of the Thracian region.
Those who pay attention to this fact are rare and few, because most focus on the catastrophe of Smyrna.
The substance of the matter is quite simple.
As much as Smyrna was important to us, it never constituted a danger for Turkey.
Whereas on the contrary Thrace, as insignificant and it may appear to many of our own, because of its location, its nature, and due to strategy, it remains an intertemporal risk for it.
It considers, that this side isn’t secured, and she always wanted to be in control, or at least to avoid the existence of an attack context.
It suffers the syndrome of the conquest of Constantinople, and is always fearful of our return to the region.
So, although there was no battles in the region, she always wanted, and finally managed, to have it declared as a demilitarized zone.
It is important for us to integrate that factor in our conception, and to comprehend why even at the Sevres Treaty, they avoided to return Constantinople to us, whereas there was no substantial problem in regards to Smyrna.
Consequently, the geostrategic context of Thrace is crystal clear. The issue in question is whether it would be utilised, or it would remain as is, due servility.
