Using number of wars involved in my guess the winner would be Great Britain.
I think my humble little nation of Australia would get a mention with 13 since 1900. Not a bad effort for a peace loving people.
Boer War, South Africa: 1899-1902
Boxer Rebellion, China: 1900-1901
World War 1, all over the place: 1914-1918. It could be argued that we started it by firing at a German merchant ship trying to sneak out of Melbourne.
Russian Civil War, Russia: 1918-1920. Not sure what we were doing there.
World War 2, all over the place.: 1939-1945
Korean War, Korea: 1950-1953
Malayan Emergency, Malaya: 1950-1960
Borneo Confrontation, Malaysia/Indonesia: 1963-1966
Vietnam War, Vietnam: 1965-1973
Gulf War, Kuwait/Iraq: 1990-1991
War in Afghanistan, Afghanistan: 2001-2021
Iraq War, Iraq: 2003-2009
Operation Astute, East Timor: 2006-2013
There's also been involvement in the Cook Islands against rebels and in Papua New Guinea against rebelion Bougainville Island. Apparently they don't count as wars. We're still angry with Britain for not needing our help with the Falklands.
