Final answer:
The United States sent troops to Bosnia in 1995 to intervene in the ongoing conflict, protect civilians, and help end the war. The US played a key role in negotiating the Dayton Accords peace settlement.
Step-by-step explanation:
The main reason that the US sent troops to Bosnia in 1995 was to intervene in the ongoing conflict and help end the war. The war in Bosnia was marked by ethnic tensions and acts of genocide, particularly against Bosnian Muslims. The US, along with NATO, launched airstrikes against Bosnian Serbs and ultimately played a key role in negotiating the Dayton Accords peace settlement in Ohio. Through the peace settlement, the US aimed to protect civilians, establish a dual government in Bosnia and Herzegovina, and bring stability to the region.
