__________ helps prevent adversary action through the presentation of a credible threat of counteraction. It stems from the beli

Deterrence is military strategy under which one power uses the threat of reprisal effectively to preclude an attack from an adversary power.
Since deterrence is the use of threats to block or reduce the inflicting of serious harm, the existence of capacities for inflicting harm are readily maintained and periodically applied, so available deterrence capabilities provide a degree of continuing concern and a regular desire to at least do away with nuclear weapons and threats.
Deterrence has been employed to prevent (or at least limit) the destruction of states, societies, and ultimately humanity. The greatest success has been that no nuclear weapons have been used for destructive purposes since the end of World War II in 1945.
Archaea do still exist but only in extreme environments. Pointing to this is the fact that they were undiscovered for a while until they were eventually found in aquatic environments with extremely high temperatures.
