A new study shows that 60% of the world’s wars have lasted for at least a decade. From Afghanistan to Libya, Syria to Congo DRC, has endless conflict become normalised?

Libya’s civil war entered its 7th year this month with no end in sight. In Afghanistan, conflict has raged on and off since the Soviet invasion in 1979. America’s Afghan war is now its longest ever, part of the open-ended US “global war on terror” launched after the 2001 al-Qaida attacks.

Yemen’s conflict is in its sixth pitiless year. In Israel-Palestine, war – or rather the absence of peace – has characterised life since 1948. Somalis have endured 40 years of fighting. These are but a few examples in a world where the idea of war without end seems to have become accepted, even normalised.

Why do present-day politicians, generals, governments and international organisations appear incapable or uninterested in making peace? In the 19th and 20th centuries, broadly speaking, wars commenced and concluded with formal ultimatums, declarations, agreed protocols, truces, armistices and treaties.
