Nuclear utilization target selection
Nuclear utilization target selection (NUTS) is a hypothesis regarding the use of nuclear weapons often contrasted with mutually assured destruction (MAD). NUTS theory at its most basic level asserts that it is possible for a limited nuclear exchange to occur and that nuclear weapons are simply one more rung on the ladder of escalation pioneered by Herman Kahn.
