Outside of germany and poland most jews died in greece in the Holocaust. Salonika had a vibrant jewish population in early 1900s and now virtually no jews live in Salonika. During ottoman times greeks and jews were fierce enemies and killed each other in many occasions in Istanbul, Smyrna, Alexandria and Salonika.. Jews, mostly loyal to ottamans during the greek independence war were punished (aka murdered) by the greek army in many occasions.

"Most" as a percentage, not an absolute number. There were approximately 60.000 Jews who were murdered from Greece which amounts for 87% of the total Jewish population in the country. Hungary had some 500k loses, Poland 3M, Romania at least 200k, Soviet Union 1,3M etc.
It is true that in the Ottoman and Czarist mercantile cities, ethnic riots did involve Jews and Greeks, sometimes against each other. I should have specifically said Jewish and Greek armies.
Israel could do Greece a favor send some IDF forces to play as the Turks and war game a land invasion on the Thracian border. It would be a useful exercise for Greece because Israel's infantry capabilities map closer to Turkey's than to Greece's.
Israel has 0 island-hopping capabilities compared to Greece's ability to patrol its Aegean waters.
