The tit for tat between Germany and Turkey is increasing.
It is not just with Germany, Erdogan is already in the face of the entire world. Very bad cocktail in the Middle East.
There’s been very strong hints by the German Foreign Ministry over the last two months for Germans NOT to travel into Turkey...no one can ensure their safety. Without going to the next step....branding Turkey a dangerous place...they’ve done everything required.
The tit for tat business is pretty limited....because of the EU-deal to hold back refugees in Turkey (that 3-billion Euro a year deal). All of this business is screwing up the Turk-tourism economy big-time.
Turkiye is probably not a very good place to visit currently.
