Tension in the Strait of Hormuz: A Negotiation Tactic or a Return to High-Intensity Conflict

Policy analysis by Ameer Makhoul, Progress Center for Policies – London

Introduction:
The escalation in the Strait of Hormuz, following the U.S. administration’s decision to impose a comprehensive naval blockade, marks a pivotal moment in the trajectory of the U.S.–Iran conflict. Both sides appear to be shifting from direct negotiations to managing the conflict through layered pressure instruments that combine military and economic tools.

Despite the collapse of the Islamabad negotiation round without agreement, current indicators do not suggest a breakdown of the diplomatic track so much as its repositioning into indirect channels. This shift is driven by the persistence of a “no-decision” outcome that characterized the recent war. In this context, Washington is seeking to leverage the naval blockade as a bargaining tool to compel Tehran to accept its terms, capitalizing on its maritime superiority. However, it faces both domestic and external constraints—most notably the impact of rising oil prices on the U.S. economy, particularly amid looming electoral pressures.

Conversely, Iran views the escalation as an extension of the negotiation battlefield, grounded in the assessment that the war did not produce decisive results and that it retains the capacity to endure and impose a deterrence balance that prevents unilateral terms. These dynamics also intersect with parallel regional tracks, particularly in Lebanon, where reciprocal escalation underscores the difficulty of compartmentalizing fronts and adds further complexity to any negotiation pathway. The conflict thus enters a phase of high-risk management, oscillating between calibrated escalation and continued indirect diplomacy, with the risk of broader confrontation remaining present—though not immediately likely.

Analysis

First: The Naval Blockade as a Negotiation Lever
U.S. President Donald Trump announced on Sunday, April 12, the imposition of a comprehensive blockade on the Strait of Hormuz within 24 hours of the declaration, with participation from unnamed partner states. The stated objective is to prevent Iran from selectively controlling the passage of oil tankers based on its political relationships. Trump also instructed the U.S. Navy to detain any vessel in international waters that pays fees to Iran. Invoking the precedent of the blockade imposed on Venezuela prior to efforts to unseat Nicolás Maduro, Trump emphasized that the current measures against Iran are broader in scope and intended to force compliance with U.S. negotiation terms.

This decision reflects a transition from direct negotiations to the use of economic-military pressure tools aimed at extracting concessions without engaging in full-scale war. However, this approach faces structural challenges, foremost among them the likelihood of global oil price increases, which could adversely affect the U.S. economy—especially in the context of approaching midterm elections. Moreover, Washington does not fully control the scale or nature of Iran’s response.

Second: Suspension of Talks Does Not Necessarily Mean Renewed War
Despite the halt of the Islamabad negotiation round, it cannot be interpreted as a definitive indicator of an imminent return to war. The possibility of extending the ceasefire remains, allowing space for continued mediation efforts. Nevertheless, the U.S. naval blockade constitutes a major obstacle that could derail any diplomatic progress, given its direct economic and military implications.

The U.S. decision thus presents a dual dilemma: on one hand, the blockade is intended to increase the cost of Iranian intransigence and push Tehran back to negotiations under U.S. terms; on the other, it risks driving up oil prices domestically and globally—an outcome Trump is keen to avoid, particularly ahead of midterm elections that could threaten the Republican majority in Congress.

Still, the administration appears to be betting on the rapid impact of the blockade, anticipating that Iran will yield under mounting economic pressure. At the same time, there are no definitive U.S. signals that war is the only alternative. Official statements reflect ambiguity—between declaring negotiations “currently suspended” and keeping the door open for their resumption, with mediators continuing to play a central role. U.S. assessments also suggest that, despite deep gaps, key issues remain negotiable, including the nuclear file, the release of Iranian assets, and the status of the Strait of Hormuz.

Reports cited by Israeli Channel 13, referencing The Wall Street Journal, indicate the possibility of limited U.S. strikes against Iran. However, past experience suggests that such strikes are difficult to contain within predefined limits and could trigger gradual escalation leading to a new round of conflict—especially given Washington’s limited ability to fully control Iranian responses or Israeli behavior, which may seek to disrupt negotiation tracks.

In this light, the partial U.S. withdrawal from negotiations can be understood as a tactical maneuver within the broader negotiation process rather than a definitive exit. The same applies to measures in the Strait of Hormuz, including restrictions on Iranian-linked oil transport—they are instruments of pressure, not resolution. Iran’s conduct similarly reflects a calculated management of the negotiation process, with both sides recognizing that neither war nor negotiations have produced decisive outcomes, keeping diplomacy a viable option.

At the level of narratives, Tehran advances a counter-narrative to the U.S.–Israeli position, claiming it was close to reaching an agreement before being confronted with maximalist U.S. demands, including altered conditions and the imposition of a blockade. Conversely, U.S. and Israeli assessments point to a relative decline in American influence during the war—both internationally and domestically—necessitating a recalibration of U.S. conflict-management tools.

Third: Escalation Risks and the Multiplicity of Actors
Israeli statements, including warnings from military leadership about the possibility of a preemptive Iranian strike, reflect the persistence of a “preemption doctrine” that preceded the war. This discourse inherently justifies the expansion of military operations.

In this context, Prime Minister Benjamin Netanyahu seeks to reframe the war’s outcome domestically by claiming it prevented Iran from acquiring nuclear capabilities that threaten Israel’s existence—an effort to consolidate his political standing against internal rivals. However, the multiplicity of actors and divergence in their calculations make it difficult to control escalation dynamics. Washington does not solely determine the pace of escalation, nor can it guarantee that limited operations will remain contained, thereby increasing the risk of unintended broader confrontation.

Fourth: Intersecting Regional Tracks – The Lebanese Case
There is an internal Israeli conviction that the Lebanese and Iranian files can be decoupled, effectively ending the concept of “unity of arenas” at the regional level. However, there is no equivalent confidence in the military’s ability to resolve key issues such as disarmament. The Netanyahu government has shown little interest in political negotiations with the Lebanese state, given the sovereignty implications involved. Instead, it favors security-driven approaches in Lebanon, Gaza, and Syria, while publicly adopting negotiation frameworks largely under U.S. pressure. Its preference remains military resolution and the consolidation of security control over southern Lebanon—potentially without its inhabitants.

Despite this trajectory, some view U.S.-sponsored talks with Lebanon as an opportunity to sideline broader Arab and international involvement, particularly that of France, Egypt, and Saudi Arabia. The Lebanese front is experiencing simultaneous escalation alongside tensions in the Strait of Hormuz, highlighting the clear interconnection between regional tracks. While the United States appears to accept Israel’s approach of separating the Lebanese file from the Iranian one, Israel itself lacks the decisive capacity to impose final security arrangements, including disarmament.

Meanwhile, the Lebanese state seeks to restore sovereignty, end Israeli occupation, and limit Iranian influence—creating additional internal tensions and further complicating the landscape. U.S.-exclusive mediation also opens the door to reshaping regional balances by marginalizing other Arab and international actors.

Conclusions
-U.S. escalation measures, alongside Iranian responses, indicate a transition toward reciprocal pressure aimed at reshaping negotiation terms without reverting to full-scale war, reinforcing the role of mediators in sustaining ceasefire extensions and reopening talks.
-Rising oil prices—globally and within the United States—constitute a significant external constraint on the Trump administration, forcing a careful balance between negotiation objectives and domestic political considerations, particularly in the sensitive energy context of electoral cycles.
-Despite a relative decline in direct Israeli influence on U.S. decision-making following intelligence miscalculations, Netanyahu retains the capacity to exploit internal divisions within the U.S. system to push for more hardline options, including obstructing negotiations or expanding escalation.
-U.S.-mediated Lebanese–Israeli talks appear limited in scope due to sovereignty complexities and Israel’s reluctance to engage fully with these obligations, making it likely that the costs of a ceasefire in Lebanon will be integrated into the broader negotiation framework with Iran, including the role of Tehran-aligned actors.
-The overlap between regional tracks—particularly in Lebanon—underscores the high complexity of the strategic environment, where negotiation files can no longer be isolated from their operational extensions on the ground
