Intelligence alliances are cooperative agreements between countries or organizations to share information and resources related to national security and intelligence operations. These partnerships enhance the ability to detect and respond to threats, such as terrorism or cyberattacks, by pooling knowledge and expertise. Such alliances often involve formal agreements, joint training exercises, and the exchange of intelligence reports. Notable examples include the Five Eyes alliance, which consists of Australia, Canada, New Zealand, United Kingdom, and United States, working together to monitor global security issues and share critical information.
