Just before Alexis Tsipras was elected Greek prime minister in January, he made a vow to the voters: “On Monday national humiliation will be over. We will finish with orders from abroad.”

Anyone tempted to dismiss this stress on national humiliation as a Greek eccentricity should look around the world. When I think about the four international issues that I have written most about over the past year — Russia, the eurozone, the Middle East and east Asia — a theme that links all of them is the rhetoric of national or cultural humiliation.

One of Mr Tsipras’s first acts as prime minister was to visit a memorial to Greek resistance fighters executed by the Nazis in the second world war. This gesture was all about national pride: reminding voters of past heroism while inflicting a little return humiliation on the Germans, who led the pack of eurozone creditors.
