It will be a real crisis of one NATO member makes war on another.
Why are you linking to this? Greeks and Turks - both Nato members - have been rivals, to put it mildly, for a very long time. There are many Turks who would like to see the restoration of the Ottoman empire and the extended reach of Ankara’s regional control. Erdogan has accorded himself the powers of a Sultan - just as Putin has unleashed his inner Tsar. Why do you think this link should invite comment or discussion?
Do you see Turkey invading and annexing any of the Greek territory? Would you agree with the invasion pretexts of historical boundary restoration, or defense of Muslims or Turkish-speaking peoples in the territory? Is the presentation of this map of interest as an illustration of emboldened imperialism in the wake of the Russian war in Ukraine? First Russia takes back Ukraine; then China threatens Taiwan; then Turkey claims “half the Aegean”.
