Synonyms for intermediate range ballistic missile include IRBM, medium-range ballistic missile, mid-range ballistic missile, and theater ballistic missile. These missiles typically have a range of between 1,000 and 5,500 kilometers and are designed to deliver nuclear or conventional warheads to targets beyond a country's immediate borders. The development and deployment of these missiles is often a source of tension between nations, and their use can escalate regional conflicts into global crises. In recent years, several countries, including North Korea and Iran, have been developing and testing these missiles, leading to calls for increased international cooperation and arms control measures.
