The duration of modern interstate conflict is rarely determined by the depletion of physical munitions; it is governed by the convergence of political willpower and the attainment of specific security thresholds. When Israeli Foreign Minister Gideon Saar asserts that the conclusion of hostilities with Iran rests solely with Jerusalem and Washington, he is not making a rhetorical claim, but defining a specific asymmetric power dynamic. This conflict operates on a timeline dictated by the superior party’s tolerance for risk and its definition of a "stable end-state."
To understand the mechanics of this war, one must look past the daily exchange of kinetic strikes and analyze the underlying structural logic. The conflict is not a peer-to-peer struggle for survival, but a calibrated campaign to recalibrate the regional order.
The Triad of Terminal Conditions
The end of any military engagement requires the fulfillment of three specific variables. If these variables are not met, the conflict enters a state of perpetual low-intensity friction.
- Capability Degradation Threshold: The point at which the adversary’s offensive infrastructure—specifically drone production, ballistic missile silos, and command-and-control nodes—reaches a level of attrition that renders further strikes statistically insignificant.
- Proxy Decoupling: The severance of the logistics and financial umbilical cord between the central Iranian IRGC (Islamic Revolutionary Guard Corps) and its regional affiliates in Lebanon, Yemen, and Iraq.
- Domestic Political Alignment: The synchronization of Israeli and U.S. domestic interests. In 2026, this alignment is increasingly focused on preventing a nuclear breakout while avoiding a "forever war" scenario that drains Western treasury and focus.
The Cost-Benefit Calculus of Escalation
The "War with Iran" is a misnomer in the traditional sense. It is a series of multi-domain operations. We must evaluate the current strategy through the lens of a Cost-Function of Containment.
For Israel, the cost of inaction (a nuclear-capable Iran) far outweighs the cost of active kinetic engagement. For the United States, the calculation is more complex, balancing global energy stability against the necessity of maintaining a credible deterrent in the Middle East.
The Mechanism of Pre-emptive Deterrence
The current strategy utilizes a mechanism known as "mowing the grass," but with a significant shift toward "root extraction." Traditional deterrence sought to influence Iranian behavior through the threat of retaliation. The new doctrine, signaled by Saar’s comments, focuses on denial of capability. If the U.S. and Israel decide when the war ends, they are stating that the war only ceases when Iran no longer possesses the means to escalate, regardless of its will to do so.
Structural Bottlenecks in the Conflict
The primary bottleneck for a definitive conclusion is the Sovereignty Gap. While Israel can degrade the IRGC's assets in Syria or Lebanon, striking the Iranian mainland carries a different set of geopolitical consequences. This creates a circular dependency:
- The Israeli Constraint: Israel has the tactical intelligence to strike high-value targets but requires U.S. diplomatic cover and refueling/logistics support for long-range, sustained campaigns.
- The U.S. Constraint: The United States possesses the heavy-ordnance capability to neutralize hardened underground facilities (like Fordow) but is hesitant to trigger a global oil price shock.
This interdependence means the "decision" to end the war is actually a negotiation of risk-sharing between Washington and Jerusalem.
The Logistics of the End-State
The conclusion of hostilities will not be marked by a treaty or a formal surrender. Instead, it will be characterized by a Strategic Transition Phase. This phase occurs when the marginal utility of further airstrikes decreases relative to the diplomatic gains of a new regional security framework.
Operationalizing the "Decision"
When the Israeli Foreign Minister references the decision-making power of Israel and the U.S., he is highlighting three operational levers:
- Maritime Interdiction: The ability to seize or sink vessels transporting oil or weaponry, effectively starving the Iranian economy and its proxies simultaneously.
- Electronic and Cyber Neutralization: The deployment of non-kinetic assets to disable Iranian air defenses, creating a "permissive environment" for future strikes.
- Sanction Convergence: Moving beyond symbolic sanctions to a total secondary-sanction regime that forces Iranian trading partners to choose between the Iranian market and the USD-denominated global financial system.
The Intelligence-Strike Feedback Loop
The efficiency of this conflict is driven by the speed of the intelligence-to-strike cycle. In previous decades, identifying a target and executing a strike took days. In the current 2026 operational environment, this has been compressed to minutes. This compression means that the superior technological power can exhaust the adversary’s strategic reserves at a rate that far outpaces their ability to replenish them.
The war ends when the Replacement Rate of Iranian assets falls below the Attrition Rate for a sustained period of six months. At this point, the Iranian leadership faces a binary choice: preserve the regime by de-escalating, or risk total institutional collapse by continuing a fight they can no longer physically support.
Critical Risks to the Framework
No strategy is without vulnerabilities. The reliance on U.S.-Israeli alignment assumes a static political environment. However, structural shifts could disrupt this "decision-making" monopoly:
- Third-Party Intervention: If a secondary power, such as Russia or China, provides advanced S-400 or S-500 air defense systems to Iran, the cost-function for Israeli strikes increases exponentially.
- Internal Israeli Volatility: Domestic protests or coalition shifts in the Knesset could fracture the consensus on the "End-State" definition.
- Economic Contagion: If the conflict expands to the Strait of Hormuz, the global economic fallout could force a U.S. withdrawal from the kinetic aspects of the strategy.
Strategic Forecast for Operational Continuity
The war will likely enter a terminal phase not through a ceasefire, but through a Shift to Managed Friction. This involves the establishment of a "Red Line Architecture" where any Iranian movement toward nuclear enrichment above 60% or the transfer of hypersonic missiles to proxies triggers an automated, pre-approved military response.
The center of gravity in this conflict has moved from the battlefield to the laboratory and the central bank. The physical war ends when the technological and economic gap between the US-Israel bloc and the Iranian regime becomes unbridgeable.
Strategic victory requires the transition from Active Neutralization to Automated Containment. This involves the permanent deployment of high-altitude long-endurance (HALE) drones and persistent satellite surveillance to ensure that any attempt by Iran to rebuild its offensive infrastructure is met with immediate, targeted attrition. The "decision" to end the war is thus the decision to stop the active phase and begin the permanent monitoring phase.
The objective is not a peaceful Iran, but an irrelevant one.
