Defense partnerships are cooperative agreements between countries aimed at enhancing their military capabilities and security. These partnerships can involve joint training exercises, sharing intelligence, and collaborating on defense technology. By working together, nations can better address common threats and improve their overall defense readiness. Such partnerships often include formal alliances, like NATO, or bilateral agreements between countries, such as the U.S.-Japan Security Alliance. These collaborations help strengthen diplomatic ties and promote stability in regions facing security challenges, ensuring that partner nations can respond effectively to potential conflicts or crises.
