"The turkish people have had decades of not being able to afford a passport. Access to Europe, has been the search for a golden fleece, for millions."
Load of rubbish. Getting a passport isn't a problem. Getting the travel visa is the problem - expensive and necessitates loads of documents, proof of money in the bank, DC.
"Withdrawing the (visa) deal will turn turkish public opinion against Erdogan"
Hahahahahhhaaahah! Are you fucking kidding me?
(1) Nobody cares about visas right now. Erdogan has them waving flags in the streets every night. No foreign decision will turn public opinion against him.
(2) Erdogan severely restricted international travel for Turkish passport holders, anyway. You can't leave the country if you have a green passport (i.e. civil servants). Even with a normal passport, you have to get a document from the state saying that you don't work for the government (justice, education, bureaucracy, etc) and that there is no problem with you leaving the country.
And you think visas are what Turks care about right now?
