There's no doubt that Canadians have developed a full-blown, if heartbreaking, romance with their soldiers - and, it can be argued, a more robust sense of the country's place in the world. They have become modern-day action heroes, fighting the Taliban in lethal skirmishes, chasing pirates off the Somali coast, providing a worthy air escort for the Olympic torch across the ocean. But it's an awkward love affair.

If Canadians have accepted - and even come to admire - a military that is more muscular, they are still more comfortable with Joe, the Canadian of that decade-old beer ad who declared: “I believe in peacekeeping, not policing.”

Yet after decades of keeping the peace, Canadian soldiers have become police - immersed in a deadly combat mission which, according to several polls, a majority of Canadians oppose. While tending to accept that their soldiers should stay in Afghanistan to the 2011 deadline, a war-shy public will be hesitant to commit to a future of grieving over the Highway of Heroes, however renewed their patriotism. Afghanistan, some analysts say, may be the country's last war, at least for a while. So a hard conversation looms when the fighting side of the mission ends two summers from now: Welcome home, brave soldier. But where and how will you serve next?

“The question facing Canadians - and it's very important - is what do we want to do with a better armed, better equipped, better funded military,” says Janice Stein, director of the Munk Centre for International Studies at the University of Toronto. “Are we willing to use it? That's the debate that's coming.”

For a country shaped over the past 50 years by its peacekeeping identity, that means a truth-telling: “Classic peacekeeping of the kind where you interpose yourselves between two armies and play volleyball in the middle, that's gone.” Now wars are fought inside countries between armies and militants, and civilians are killed deliberately. In Afghanistan, Dr. Stein observes, “we can talk about it as a reconstruction mission or stabilization mission, but that actually involves fighting and dying. [That makes] many Canadians uncomfortable still.”
