My French aunt died the other day. She was lovely woman. But sadly she was also a terrorist.
Born British, she had married a member of the French World War II Resistance forces fighting the Nazi occupation of their country. He had been betrayed by another Resistance fighter under Nazi torture, himself tortured and then killed. She had survived the next three years in a German slave-labor camp.
At the war's end, she was brought back to France as a heroine. But the fact remains that she and others in the Resistance had used violent, undercover force against the established authorities. By today's standards that is "terrorism." And that is what the Nazis thought too.
