The war in Bosnia was widely covered by the world media, and world public opinion denounced the actions of the Serbs. Despite this, no major steps were taken to end the genocide. Extensive international negotiations and deliberations regarding the question of intervention in Bosnia allowed the genocide to take place with no country acting to end it. Only in mid-1994 did the picture change. The United States intervened by offering Milosevic economic incentives in exchange for a peace agreement. A rift was created between Serbia headed by Milosevic and the Serbs in Bosnia. Violence continued until August 1995, when NATO forces began attacking the Serbs from the air, which led to the Serbs’ surrender and the end of the war in Bosnia. The Dayton Accords, signed after the war, split Bosnia into separate Serb and Muslim autonomous regions. The Serbs stayed in Bosnia.
