In these years, Canada defined its international role through participation in organizations like the United Nations and NATO. Such participation ranged from sending military observers to fighting forces. In Korea, Canada initially participated in a UN treaty commission (1948-49) and then became a combatant in the Korean War (1950-1953) . The apex of Canada's diplomatic achievements came with the awarding of the Nobel Peace Prize to Lester B. Pearson in 1957 for his work in resolving the Suez crisis.
