Before getting to his criticism of my case against the war in Afghanistan1, Professor Barry Cooper spends the first half of his article on his various objections to libertarianism. In his first paragraph, he asks, “What is libertarianism?” and adds, “Henderson does not provide us with an account of what he means.” There’s a reason I didn’t define libertarianism: I never used the words “libertarian” or “libertarianism.” That was a word that the editors of this publication put in the title of my article.

Shortly after the U.S. government’s attack on Afghanistan in October 2001 (which, of course, followed the September 11 attacks on the United States), the Canadian government joined the United States, the United Kingdom, and other countries in an occupying coalition in Afghanistan. The first major wave of Canadian troops arrived in Afghanistan in February 2002.
