That's not likely now, or perhaps ever.

Last week, President Recep Tayyip Erdogan compared Angela Merkel's Germany to Hitler's, said the Netherlands was full of "Nazi remnants" and "fascists," and suggested the Dutch ambassador go home.

What precipitated Erdogan's outbursts?

City officials in Germany refused to let him campaign in Turkish immigrant communities on behalf of an April 16 referendum proposal to augment his powers.

When the Netherlands denied Turkish Foreign Minister Mevlut Cavusoglu landing rights, he exploded, saying: "The Netherlands … are reminiscent of the Europe of World War II. The same racism, Islamophobia, xenophobia, anti-Semitism."
