Greek Prime Minister Kyriakos Mitsotakis has faced significant national security challenges during his tenure, including a massive operation to prevent an influx of migrants stemming from a hybrid attack by Turkey in February 2020. During this time, Turkey opened its borders at the Greek-Turkish border in Evros, prompting Greece to reinforce its borders effectively. Additionally, a naval crisis in the Mediterranean occurred in August 2020 when Turkey dispatched the seismic research vessel Oruc Reis into Greek territorial waters, leading to near clashes between Greek and Turkish frigates that could have resulted in severe and unpredictable consequences.

These events highlighted Greece's improved crisis management capabilities, contrasting starkly with the near-war scenario experienced during the Imia crisis in January 1996. At that time, tensions between Greece and Turkey escalated to a dangerous level, reminding of the potential for conflict in the region. The Mitsotakis administration's handling of these situations shows that Greece has learned from past experiences, enhancing its approach to national security.

In response to evolving military and hybrid threats, Greece is pursuing a multi-layered national security strategy, incorporating cybersecurity among other elements. This comprehensive approach aims to ensure a well-coordinated response to threats at both the regional and international levels, recognizing the complex nature of contemporary security challenges, especially in light of ongoing tensions with Turkey.
