When did what happen? My best guess is sometime between 1939 and 1945.
The First World War (WW1) 1914-1918 The Second World War (WW2) 1939-1945
Wars fought by industrial nations (world powers/civilized nations/etc. etc.) after 1945 cannot be full fledged all out wars (more simply referred to as "total wars"). Because of MAD, mutually assured destruction from atomic weapons. Wars fought prior to 1945 (prior to the invention of nuclear weapons) could be fought as total wars. Total War=Anything goes
All out total declared wars...until 1945 and the atomic bomb. From that date (1945) onward (to today), limited wars (Korea and Vietnam); and Military Operations (Urgent Fury-Grenada, Just Cause-Panama, Desert Storm-Iraq, Restore Hope-Somalia, Iraqi Freedom-Iraq, Enduring Freedom-Afghanistan, etc.) are now the norm.
did it end in 1945 has there been anymore wars since the 2nd world war
World War 2 in Europe (1939-1945).
The Eighty Years' War (1568-1648) The Second World War (1939-1945)
