Someday, I have no doubt, the dead from today's wars will be seen with a similar sense of sorrow at needless loss and folly as those millions of men who lie in the cemeteries of France and Belgium - and tens of millions of Americans will feel a similar revulsion for the politicians and generals who were so spendthrift with others' lives.

Many of the principle weapons that the Nazis used during World War II had their first trial in combat in Spain - the Messerschmitt 109 fighter plane for example, the Stuka dive bomber, the 88 millimeter artillery piece, which could be used both for antiaircraft purposes and also shelling on the ground. And American soldiers were the victims of these things in Spain, American volunteers. So this war was really a testing ground for Hitler. And he learned a great deal from it about the strengths and weaknesses of these different weapons.

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.

The first World War in so many ways shaped the 20th century and really remade our world for the worse.

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?

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.
