The phrase "divide and conquer" in political strategy refers to the tactic of creating or exploiting divisions within a group to weaken it and prevent unified opposition. By fostering conflict among potential adversaries, a leader can maintain control and power more easily. This strategy can manifest in various forms, from promoting differences based on ideology or identity to inciting competition among factions. While effective in the short term, this approach can ultimately harm social cohesion and result in long-term political instability, as it undermines collaborative efforts and trust among communities.
