Any war is too much war. That said, from 1995 to 2010 there were fewer, less lethal wars each year. This was the peace dividend from the end of the Cold War in 1990, along with a reduced risk of nuclear conflagration and the use of more economic resources for peaceful purposes. It was possible because international co-operation increased and helped end wars and monitor peace agreements.
But those gains have not been sustained. Since 2010, the number of wars has increased, the number of international peace operations has declined, the number of new peace agreements has fallen away, and the rate of casualties from war has risen sharply.
