War-weariness

War-weariness is the public or political disapproval for the continuation of a prolonged conflict or war.

It also occurs when a belligerent has the ability to leave the conflict easily but continues to stay.

War-weariness normally leads to a distrust in government or military leadership and can spark protest and anti-war movements.

It can also be fueled when a belligerent is found guilty of war crimes, which can create domestic and international backlash.
