US Editor Warns Against Nuclear Strike on Iran

Tyler Rogoway, editor-in-chief of the US military outlet The War Zone, has publicly warned that the United States and Israel should not use nuclear weapons against Iran’s nuclear facilities. The significance of his statement lies not in any new tactic it proposes, but in the line it touches: nuclear weapons have not been used in combat since 1945, and using one against a nuclear facility would break two unwritten rules at once — the taboo on using nuclear weapons and the taboo on attacking civilian nuclear sites.

What the warning targets

Iran’s nuclear facilities are mostly underground or hardened, and whether conventional bunker-busters can fully destroy them has long been disputed. In discussions about a “one-time solution,” some argue that only a low-yield nuclear bomb can guarantee destruction. Rogoway’s warning is aimed at exactly this line of thinking: once nuclear weapons are treated as an engineering tool for hitting hardened targets, the nuclear threshold drops from “a threat to the nation’s existence” to “a routine military operation,” and any nuclear-armed state could later invoke the same logic.

Once the nuclear taboo weakens

Nuclear weapons have gone unused for more than 70 years not because of treaties, but because of a near-instinctive taboo. Its defining feature is that it does not distinguish between the size of a country or the strength of a justification — only whether the line is crossed. If the United States or Israel were the first to drop a nuclear bomb on Iran’s nuclear facilities, the biggest casualty would not be Tehran’s centrifuges but the taboo itself. After that, every deadlock in a regional conflict where “conventional means won’t work” would bring calls for the nuclear option, and opponents’ arguments would be weakened.

Speculation on Zhihu

Answers on Zhihu extended the warning into a series of scenarios: some respondents argued that needing nuclear weapons against a country of Iran’s size itself shows the limits of conventional means; others, following the “precedent” logic, imagined that once the nuclear threshold is breached, other nuclear states might follow suit on different battlefields, shaking the nuclear balance from Europe to South Asia. These scenarios are clearly exaggerated, but the question they point to is real: the restraining power of the nuclear taboo depends on consensus, and once that consensus is broken first by the most capable countries, it is very hard to repair.

A notable disagreement

Another view holds that the warning itself shows decision-makers understand the weight of this line, and that public dissuasion is precisely the restraint mechanism at work. The key disagreement is whether nuclear weapons are a “last resort” or a “usable tool.” The former requires that they not be considered until every conventional option is exhausted; the latter only requires arguing that they are “militarily effective.” Rogoway’s warning stands on the former side, and whether such warnings work depends on whether they are truly heard.

Dropping a nuclear bomb on a nuclear facility may allow one to calculate the blast radius militarily, but the political consequences cannot be calculated. The fact that this line is being discussed at all already means
