What kind of war makes a country even begin to think about nuclear weapons?

 

This unsettling question resurfaced on March 14, 2026, after a remark from Washington sparked renewed strategic debate. During the “All-In” podcast, David Sacks, an adviser to U.S. President Donald Trump, warned that a prolonged war between Israel and Iran could push the conflict into extremely dangerous territory.

 

Sacks did not advocate the use of nuclear weapons. Instead, his warning highlighted a deeper concern: prolonged wars can drive governments into situations where leaders consider options that would normally be unthinkable.

 

His remarks were later reported by Shafaq News and Newsweek, prompting renewed discussion among security analysts about the conditions under which Israel might even contemplate such an extreme scenario.

 

Understanding this question requires examining how Israel views its own security.

 

Israel lacks significant strategic depth. Its major cities, economic centers, and military infrastructure are concentrated within a relatively small geographic area. Strategically, Israeli leaders have long believed the country cannot afford a catastrophic defeat.

 

For this reason, Israeli strategists often approach national survival differently from their counterparts in larger states. If a war were to threaten the basic functioning of the country, the pressure on decision-makers could become immense.

 

Another critical factor is Israel’s perception of Iran’s regional role.

 

Israeli leaders have long described Iran’s nuclear ambitions and missile capabilities as existential threats. Iran’s support for armed groups such as Hezbollah in Lebanon, Hamas in Gaza, and various militias operating across the Middle East is viewed in Israel as a major security challenge.

 

Because of this network of regional actors, Israeli strategists frequently view a confrontation with Iran not as a limited conflict but as a potential catalyst for a wider regional war.

 

This perception has shaped Israel’s long-standing security doctrine. Israeli strategy traditionally emphasizes deterrence and overwhelming military response in order to prevent adversaries from believing they can defeat the state.

 

Historically, Israel has also carried out pre-emptive strikes against regional nuclear programs, including the Iraqi nuclear reactor in 1981 and a suspected Syrian nuclear facility in 2007. These actions reflected the belief that allowing hostile states to acquire weapons capable of threatening Israel’s survival would be unacceptable.

 

As a result, analysts often describe Israel as a country that believes it must act before threats become irreversible.

 

If a prolonged conflict with Iran led Israeli leaders to conclude that conventional military power could no longer guarantee national security, strategic discussions inside government circles could become far more severe.

 

Modern warfare adds another layer of pressure.

 

Iran possesses a substantial arsenal of ballistic missiles and drones, while Israel relies heavily on layered missile-defense systems, including Iron Dome, David’s Sling, and Arrow. These systems are highly capable, but they are not infallible.

 

If a long war were to produce sustained missile saturation, hundreds of missiles launched repeatedly over weeks, the economic and psychological pressure on Israeli society could become severe.

 

Strategists warn that the danger in such scenarios extends beyond battlefield losses. The real risk could be systemic strain, where air defenses are stretched, infrastructure is damaged, and civilian casualties rise.

 

In such crisis conditions, leaders may begin to fear that the conflict is moving beyond the limits of conventional warfare. Governments sometimes start considering options that previously existed only as theoretical deterrents.

 

A deeper historical dimension also shapes Israeli strategic thinking.

 

The phrase “never again” functions not only as a moral statement in Israel but also as a political principle guiding national security. Many Israeli leaders interpret their responsibility through this historical lens, emphasizing that the Jewish state must never again face a situation in which it cannot defend its people.

 

This historical memory strongly influences how existential threats are perceived within Israeli political culture.

 

These factors explain why analysts sometimes discuss nuclear escalation when examining worst-case scenarios in a major Israel–Iran conflict.

 

This does not mean such an outcome is likely. Most experts believe the use of nuclear weapons would bring catastrophic humanitarian and political consequences, destabilizing the Middle East and potentially triggering a global crisis.

 

For this reason, nuclear escalation remains widely viewed as extremely unlikely. However, history shows that prolonged wars can push nations toward decisions once considered impossible.

 

David Sacks’s remarks on March 14 should therefore be understood not as a policy proposal, but as a warning about how dangerous long conflicts can become.

 

The principal danger is not simply the existence of nuclear weapons.

 

The real danger begins when leaders start believing their country’s survival may depend on using them.
