The united nations was established so that it could resolve conflicts between nations by : launching military attacks. forming blockades. imposing sanctions. occupying border countries.

My answer would be imposing sanctions.  When sanctions are imposed on a country it can hurt it both politically and economically.  This is true when member countries give their full support to U.N. sanctions.  A good example would be when South Africa still practiced Apartheid.  Because most countries didn’t support that policy, they  withdrew their support and South Africa was isolated for a long time.

C. imposing sanctions
