Your country doesn't have strategic position
From all the arguments I’ve read this is the most hilarious. Dude, have you opened a map lately? Half of Middle East is in flames including parts of northern Africa. And we have no strategic position? Greece is what stands between Europe and legions of refugees from Syria, Afghanistan and Iraq. Not to mention the fuckers from ISIS who want to infiltrate Europe. Thank God we’re in NATO otherwise we could allow Russia to build a naval base in Greece and watch EU and US go ballistic.
I though strategic position for business. Of course, you have strategic position for war but it will not bring you any money if NATO moves forces to your country to protect Europe against Middle East and North Africa.
It also funny you mention you are what stand between immigrants and Europe but I guess you forgot to mention you don't protect your borders anymore because you cannot afford it anymore so thousands of immigrants through your country is flooding Europe.
You were quite lucky you were only non-communist country in that region 30 years ago and you joined EU. EU for last 30 years was sending you approximately 6 billions EUR every year.
At least you are popular tourist destination. Good luck, I wouldn't want to be a Greek.
