Why a US-Iran Deal and a Lebanon Ceasefire Do Not Align With Israel?

By Elijah J Magnier –

Since October 2023, the Middle East has entered one of its most volatile and transformative periods in decades. The wars and confrontations that followed reshaped regional alignments, intensified rivalries, and exposed the limitations of military power even for heavily armed nations backed by major international alliances. Within this context, the possibility of a US-Iran agreement and a ceasefire in Lebanon carries implications that go far beyond diplomacy or battlefield considerations. For Israel’s current leadership, and especially for Prime Minister Benjamin Netanyahu, such outcomes present serious undesired strategic and political risks rather than opportunities.

A US-Iran understanding, even a limited one focused on de-escalation, would undermine the central narrative that has guided Israeli policy toward Iran for years. At the same time, ending the war in Lebanon without achieving decisive military objectives against Hezbollah would reinforce perceptions that Israel failed to achieve its objectives and impose its will despite escalation and destruction. These dynamics are closely tied to Netanyahu’s political survival, which increasingly depends on maintaining a permanent state of confrontation rather than accepting outcomes that can be interpreted domestically as defeat, compromise, or strategic exhaustion.

For decades, Israeli strategic doctrine relied heavily on deterrence. The country cultivated the image that military superiority, technological dominance, and rapid offensive action could neutralise threats before they evolved into long-term dangers. That doctrine depended not only on battlefield victories but also on psychological perception. Israel’s regional enemies needed to believe that escalation against Israel would carry unbearable costs and little chance of success.

The events after October 2023 severely challenged this framework. Instead of quickly ending conflicts on multiple fronts, Israel found itself engaged in prolonged warfare against non-state and regional actors capable of sustaining pressure over time and heavy losses. Hezbollah maintained operational capacity despite sustained strikes in Lebanon. Hamas survived extensive military campaigns in Gaza. Ansar Allah in Yemen demonstrated an ability to disrupt maritime routes and project influence far beyond Yemen’s borders. Iran itself proved willing to directly exchange attacks with Israel in unprecedented ways.
