Dayton Accords end the Bosnian War (1995)
US-led pressure forced Bosnia's warring factions into talks at an Ohio air base. The resulting accord ended nearly four years of war that killed around 100,000 people.
The fighting stopped and a NATO force deployed to enforce the peace.
Bosnia got an awkward but durable settlement that has held for three decades.
It is a model of external powers using leverage and the threat of penalties to end a war the combatants would not stop on their own.
