Exhaustion from prolonged violence ends civil wars. [causal]
In 1962, a popular slogan heard among exhausted Algerians was “Seba’a snin, barakat!” (“Seven years, that’s enough!”) Yet, five decades after independence, a savage war still continued in Algeria. It was a country exhausted by seven years of senseless violence, of not knowing who were the “good guys” and who the “bad.” As much as any other factor, it was this exhaustion that helped bring the civil war to an end.
