Pserimos is part of the Dodecanese island group and part of the Greek territory after the 1947 peace treaty with Italy, so I don't know what are you talking about....
Indeed, you can't compare the two sides. Turkey has x8 times our population and a significant defence industry, but sorry I don't care about your missions in Syria...I am just stating your president's statements about Greece, we find it hilarious too!
Don't pay attention to these statements, they are for internal consumption...the same tactics that erdogan has implemented! "we will suddenly come one night" type of statements...
