second strike

Retaliatory military attack

Second strike refers to a retaliatory nuclear attack launched after an enemy has already struck first.

The concept is central to deterrence theory—a nation's ability to absorb a first strike and still deliver devastating retaliation discourages adversaries from attacking: The submarine fleet ensures second-strike capability.

The term contrasts with first strike, a preemptive attack intended to destroy an enemy's weapons before they can be used.
