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.

No international court can ever substitute for a working national justice system. Or for a society at piece.

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.

Even [Ernst] Hemingway, perhaps the most intentionally non-political of American writers, became passionately partisan during the Spanish Civil War.

Ronald Reagan perfected the subtler version long ago by talking about "welfare mothers" - a code phrase for people of colour.

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.

I think writers can respond by writing about the refugee crisis, by looking at problems faced by migrants, by trying hard to portray them as the human beings that they are.
