Yes, and the Germans, as well as the rest of the EU member states should ignore the EU as a whole, end it, and regain their sovereignty.
Europe should ignore Turkey’s ‘visa blackmail’ over refugee deal – German vice chancellor

It depends on Ankara whether Turks will enjoy visa-free travel to Europe, Germany’s vice chancellor has said, adding that it was the right decision to ban a live broadcast by the Turkish president to a rally in Cologne on the weekend.
“It is up to Turkey if there is or there isn’t visa liberalization,” Reuters quoted German Vice Chancellor Sigmar Gabriel as saying while on an official visit to northern Germany.
“Germany and Europe should under no circumstances be blackmailed,” Gabriel added.
The vice chancellor also welcomed the move by Germany’s highest court to block a livestream address by Turkish President Recep Tayyip Erdogan to a rally of Turkish nationals in Cologne on Sunday.
