sentences:  A feature of strategic nuclear weapons, especially in the transcontinental nature of the Cold War, with continent-spanning superpowers that are oceans apart, is the greater range of their delivery apparatus, such as ICBMs, giving them the ability to threaten the enemy's command and control structure and national infrastructure even though they were based many thousands of miles away in friendly territory.ICBMs with nuclear warheads are the primary strategic nuclear weapons, and short-range missiles are tactical.In addition, while tactical weapons are designed to meet battlefield objectives without destroying nearby friendly forces, one main purpose of strategic weapons is deterrence under the theory of mutually assured destruction.
