Anyone can make a war. It takes something special to make a peace. For the following I am very proud of my country:

Canada and peacekeeping
A history of Canada's participation
Over 125,000 Canadian personnel have served in peacekeeping operations for the United Nations; this is more than any other country.
Although the UN began deploying peacekeepers as early as 1948, the term "peacekeeping" itself was not broadly used until 1956 when it was popularized by former Canadian Prime Minister Lester B. Pearson.

Incidentally, 'ol Lester was awarded a Nobel Peace Prize.

Anybody can start a war. These people help end them.
