<human>:  Why do countries get into wars?
<bot>: Countries get into wars for a variety of reasons, ranging from competition for resources and land to ideological differences or religious conflict. Some wars are based on longstanding disputes, while others are a result of a single event or incident that sparks a conflict. Political and economic power plays, revenge and retribution, self-defense, and attempts to protect national interests can also contribute to the decision to go to war.
