Why was James Buchanan called the do nothing president?

James Buchanan was called the "do-nothing president" due to his inaction in addressing the escalating tensions between the North and South leading up to the Civil War. His administration failed to effectively confront the secession of Southern states and the deepening national crisis, often opting for a policy of inaction and compromise. Critics argue that his reluctance to take decisive measures contributed to the eventual outbreak of the Civil War in 1861.
