Strategic weapons are advanced military systems designed to deter or defeat adversaries on a large scale. They typically include nuclear weapons, long-range missiles, and other high-impact armaments that can target critical infrastructure or military assets. The primary purpose of these weapons is to maintain national security and prevent conflicts through the threat of significant retaliation. These weapons are often part of a country's defense strategy and are managed by specialized military branches. Countries like the United States and Russia maintain strategic arsenals to ensure a balance of power, which is crucial for global stability and deterrence against potential aggressors.
