Military expenditures are the annual premium paid by Greece to address the threat of Turkish revisionist strategy. The funding of the public good of national defense is based on the economic capabilities of Greece, which consistently lag behind the performance of the Turkish economy. The unequal economic growth recorded over decades has created and largely solidified a significant gap between the Greek and Turkish economies. Over time, maintaining the existing dynamic will transform the gap into a chasm. The economic capacity to finance national defense concerns not only the power balance in the present but also determines future military correlations. In the long term, worsening economic interdependence will significantly impact military power relationships, necessitating significant changes and deep shifts in Greek defense policy to gradually and timely adapt to the economic realities of the coming decades. The chronically underperforming Greek economy could potentially become a national Achilles' heel with far-reaching consequences for Greek national interests and sovereign rights.
