Israel launched significant attacks on Lebanon, killing at least 47 people, immediately following a memorandum of understanding between Iran and the United States aimed at ending military operations. The agreement, which includes a $300 billion reconstruction plan for Iran, stipulates that the US and its allies will undertake the "immediate and permanent termination of military operations on all fronts, including in Lebanon." These Israeli actions have sparked anger and worry within Israel, with many viewing the US-Iran deal as undermining their country's interests and their perceived "special relationship" with the United States.

The timing of the Israeli strikes highlights a growing tension between Israel's objectives and the diplomatic efforts of its key ally, the US. Israeli Prime Minister Benjamin Netanyahu has reportedly been careful in his public opposition to the deal, but the military's actions and sentiments from across the political spectrum suggest a deep disapproval. The war against Iran, which Israel had long sought US collaboration on, has reportedly gone poorly for the US, leading to President Donald Trump's decision to accept a deal without apparent Israeli input. This has shifted the perceived power dynamics between the two nations.

Following the deadly strikes on Friday, four Israeli soldiers were killed overnight by Hezbollah, a Lebanese armed group. This escalation prompted a strong reaction from Israel's far-right National Security Minister Itamar Ben-Gvir, who stated that "all of Lebanon must burn." The situation remained volatile, with the agreement's future and Israel's role within it in question.

The swift Israeli response to the US-Iran agreement, particularly the extensive bombing of Lebanon, suggests a strategic defiance that could jeopardize the fragile peace accord. The effectiveness of US pressure in securing a ceasefire, reportedly agreed upon by Friday evening, will be a critical test of American influence over its ally and the viability of the broader deal.

The Israeli public and political establishment appear largely opposed to the US-Iran memorandum. A recent television poll indicated that only a small fraction of Israelis believe their country has achieved victory in the war against Iran, an adversary they have long perceived as a direct threat to their existence. This sentiment likely fuels the government's actions and complicates Netanyahu's balancing act.

Netanyahu faces a difficult challenge in navigating the demands of the US, whose diplomatic and financial support is essential for Israel, while also appeasing a domestic audience and political establishment that rejects the US-Iran deal. The extent to which he can continue to defy US policy, particularly in light of the ongoing conflict, remains a significant question.

Experts and observers have noted that the US-Iran agreement has altered long-held assumptions about the US-Israel alliance. The inclusion of a permanent termination of military operations, directly impacting fronts like Lebanon, has been met with strong resistance from Israel, which views such interventions as critical to its security.

Further developments will likely depend on the US's ability to enforce the ceasefire and manage Israel's response. The potential collapse of the US-Iran deal due to Israeli actions could have far-reaching consequences for regional stability and the broader geopolitical landscape.
