How did John Quincy Adams feel about the Missouri compromise?

John Quincy Adams had mixed feelings about the Missouri Compromise of 1820. While he recognized the necessity of maintaining the Union and preventing civil strife, he was also deeply concerned about the expansion of slavery into new territories. Adams believed that the compromise merely postponed the inevitable conflict over slavery rather than resolving it. He viewed the issue as a moral and political challenge that would need to be addressed more directly in the future.
