According to historian MacKinnon, "After the [Utah] war, U.S. President James Buchanan implied that face-to-face communications with Brigham Young might have averted the conflict, and Young argued that a north-south telegraph line in Utah could have prevented the Mountain Meadows massacre." MacKinnon suggests that hostilities could have been avoided if Young had traveled east to Washington D.C. to resolve governmental problems instead of taking a five-week trip north on the eve of the Utah War for church related reasons.
