Defense cooperation refers to the collaborative efforts between countries to enhance their military capabilities and ensure mutual security. This can involve joint training exercises, sharing intelligence, and developing defense technologies together. Such partnerships are crucial for addressing common threats and fostering stability in various regions. Through defense cooperation, nations can strengthen their strategic alliances and improve their readiness to respond to crises. Examples include agreements like NATO and various bilateral defense pacts, which facilitate resource sharing and coordinated responses to potential conflicts, ultimately contributing to global peace and security.
