The Good Neighbor policy is the 1927 reform of the Church of Jesus Christ of Latter-day Saints (LDS Church) that removed any suggestion in church literature, sermons, and ordinances that its members should seek vengeance on US citizens or governments, particularly for the assassinations of its founder Joseph Smith and his brother, Hyrum.
The church gave no official name to this process, but after it was implemented, some Mormon-history commentators began referring to it as the church's "Good Neighbor" policy,[1] taking the name from US President Franklin Roosevelt's foreign policy, the Good Neighbor policy.
