What is Nuclear Deterrence?
Historical Background
Key Points
10 points- 1.
Credibility: The threat of retaliation must be believable; the adversary must believe the state would actually use its nuclear weapons if attacked.
- 2.
Capability: The state must possess sufficient nuclear weapons and robust delivery systems (missiles, bombers, submarines) to inflict unacceptable damage on the adversary.
- 3.
Communication: The state's intent and capability must be clearly communicated to the adversary to ensure the deterrent message is received.
- 4.
Second-Strike Capability: The ability to absorb a first strike and still retaliate with devastating force, ensuring MAD and thus stability.
- 5.
Minimum Deterrence: Maintaining a smaller, but credible, nuclear arsenal sufficient to deter an attack, often adopted by states like India and Pakistan.
- 6.
Extended Deterrence: A nuclear-weapon state extends its nuclear umbrella to protect non-nuclear-weapon allies (e.g., US protecting Japan and South Korea).
- 7.
No First Use (NFU): A policy declaration by a nuclear-weapon state that it will not be the first to use nuclear weapons in a conflict (e.g., India, China).
- 8.
First Use Policy: The option to use nuclear weapons first in a conflict, often maintained by states like the US, Russia, and Pakistan, under certain circumstances.
- 9.
Escalation Control: Strategies to manage the risk of conventional conflict escalating to nuclear war.
- 10.
Arms Control Treaties: Agreements like START and INF aim to limit nuclear arsenals and enhance strategic stability, though many have lapsed.
