Nationalism makes them blind. It is officially known that They are shaking with fear When they heart the word of Turks. Their education system mentions Turks as "Uneducated Barbarians who don't know anything except fighting". Some Greek families frighten their children like "Turks are coming" (or something like that I don't remember) but They never give up their ambitious over Turkey's redlines so Desperation is the name of their destiny. Their current economical failure is also a result of their arm-race against Turkey..
Greece is the land of SAM's. You can find various type of SAM systems which was ordered from Europe, Russia to USA. S-300, Buk-M1, Tor-M1, Crotale, Aspide, PAC-2, PAC-3, I-HAWK...etc As I said You can find various type of SAM systems in their inventory. I am talking about a country which has a population around 11 million, Not USA or Russia. Only Istanbul has a population aound 15-18 million.
To use psicological effects over Greek nation, Turkish Army is also preparing lots of exercises in Aegean which is presenting a Greek island invasion scenarios with using all units. Turkish AirForces are violating their airspace daily. Such efforts drive Greeks into more depression and desperation. With this way, Before financial criss, They became Europe's biggest arm importer country ranked ahead of French and Germany and so Their economy collapsed thanks to Turkish Army. That's called as using Soft Power !!!
One of mentioned Exercise which make Greeks drive to spend more money on defencive arms, Efes-2009. (If you check the countries mostly watched this video, You will see Greeks leading. )
