Strategic deterrence is a military strategy aimed at preventing an adversary from taking aggressive actions by threatening significant retaliation. This approach relies on the credible promise of a strong response, often involving nuclear weapons, to dissuade potential attacks. The idea is that the fear of severe consequences will maintain peace and stability. Countries like the United States and Russia have developed strategic deterrence policies to protect their national interests. By maintaining a capable and ready military force, they aim to discourage conflicts and ensure that any aggression would be met with overwhelming retaliation, thereby preserving their security and sovereignty.
