Step-by-step explanation:
The organization that is established in each theater to provide a venue for interagency cooperation is typically referred to in military or governmental contexts. It is a framework designed to facilitate interagency cooperation between various agencies, both governmental and non-governmental, which are charged with protecting the territory from different types of threats. For example, this approach has been seen in counterterrorism efforts where international cooperation is crucial. Entities such as the UN Security Council's Counter-Terrorism Committee and INTERPOL work together to coordinate international counterterrorism measures. This coordination effort often involves partnering with organizations for event planning and implementation leading to expanded outreach, diversity promotion, and cost-effectiveness in resource utilization.
