Explanation:

The International Space Station (ISS) is a collaborative project among multiple space agencies. Its primary function is scientific research. It provides a microgravity environment for experiments in various fields like biology, physics, and astronomy. Ending wars is not within its scope as it is a scientific platform. Shielding Earth from asteroids is not its main purpose. While it does have some aspects of international cooperation and could be seen as a connection in a sense, the core and best - described purpose is research.
