A state cannot test its systems for eliminating an adversary's entire nuclear arsenal without the test itself being mistaken for the start of a real war. This inability to rehearse creates fundamental, irreducible uncertainty about the plan's effectiveness for any potential attacker.

The US executive branch increasingly initiates military action by citing inherent commander-in-chief powers, sidestepping the constitutional requirement for Congress to declare war. This shift, exemplified by the Venezuela operation, marks a 'third founding' of the American republic where historical checks and balances on war-making are now considered quaint.

The greatest risk of nuclear weapon use is not a peacetime accident but a nation facing catastrophic defeat in a conventional war. The pressure to escalate becomes immense when a country's conventional forces are being eradicated, as it may see nuclear use as its only path to survival.

While the US military opposes bans on autonomous 'killer robots' for conventional warfare, it maintains a firm 'human-in-the-loop' policy for nuclear launch decisions. This reveals a strategic calculation: the normative value of preventing autonomous nuclear use outweighs any marginal benefit, a line not drawn for conventional systems.

In global conflicts, a nation's power dictates its actions and outcomes, not moral righteousness. History shows powerful nations, like the U.S. using nuclear weapons, operate beyond conventional moral constraints, making an understanding of power dynamics more critical than moralizing.

Even if an attacker successfully destroys an adversary's entire command and control structure, retaliation is not prevented. Failsafe systems like Russia's 'Perimeter' or the UK's 'letters of last resort' are designed to automatically trigger a nuclear response, ensuring a second strike still occurs.

The doctrine of mutually assured destruction (MAD) relies on the threat of retaliation. However, once an enemy's nuclear missiles are in the air, that threat has failed. Sam Harris argues that launching a counter-strike at that point serves no strategic purpose and is a morally insane act of mass murder.

The rationale for Russia's automated nuclear retaliation system isn't about gaining a strategic edge. It's an internal hedge against the perceived unreliability of their own military, born from fear that human commanders might not follow a launch order, especially after a decapitation strike.

Nuclear deterrence works because the weapons provide a "crystal ball effect." Unlike WWI leaders who couldn't foresee 1918's carnage, modern leaders have a stark, pessimistic view of a nuclear war's outcome. This shared vision of guaranteed calamity creates enormous incentives to avoid starting such a conflict.
