Things have gotten openly more extreme in the last few years. I was lecturing in Hungary, whose prime minister, Victor Orban, is an example of this trend. All over Budapest, statues have been replaced, museum exhibits have been redone, to turn ethnic Hungarians, not Jews, into the prime victims of the Germans during World War II. Five years ago, who would have thought this possible?

If your real wages are declining, your job is at risk, you fear your children will be worse off than you are, it's tempting to want to blame it all on an easily identifiable target: Muslims, immigrants, refugees, blacks, Jews.

Newt Gingrich seldom misses a chance to note that he is a historian.

I think in many ways, the Spanish Civil War was the first battle of World War II. After all, where else in the world at this point did you have Americans in uniform who were being bombed by Nazi planes four years before the U.S. entered World War II? Hitler and Mussolini jumped in on the side of Francisco Franco and his Spanish nationalists, sent them vast amounts of military aid, airplanes, tanks - and Mussolini sent 80,000 ground troops as well - because they wanted a sympathetic ally in power. So I think it really was the opening act of World War II.

In Canada, the U.S. and most of Europe it may be easy to take political stands, this is something for which you can be forced to pay with your life, or your freedom, in many other parts of the world, from Iran to Russia to Pakistan to China.

How many really great writers are there who are totally non-political? You can hear the French Revolution in the poetry of [Percy Bysshe] Shelly and [John] Wordsworth; you can sense the vast inequalities of Tsarist Russia in [Anton] Chekhov and [Lev] Tolstoy.

Speaking of Germany in 1933, I don't think you can remove yourself from politics when, in so many countries - the United States, Poland, Hungary, and many others - you've got politicians in power or vying for power who are taking tactics and elements of their appeal from the playbook of fascism.
