This week, as the US-Iran war continues to escalate tensions in the region, US Vice President JD Vance unexpectedly stepped into the spotlight, reportedly leading a diplomatic backchannel aimed at ending the conflict. On one hand, he has maintained multiple rounds of calls with Israeli Prime Minister Netanyahu, trying to stabilize Israel's position, while on the other hand, he is serving as an information relay and willingness tester through the indirect communication channel with Iran that has already been initiated by Washington. In this diplomatic action disclosed by Axios and the Planet Daily, external observers are beginning to wonder: can a vice president who has long been viewed as "not hawkish enough" and skeptical of overseas wars truly tear open a gap for a ceasefire amidst the flames of conflict, or will he ultimately be constrained by the realities of politics and the pressures of allies?

From War Skeptic to Potential Chief Negotiator

Before the official outbreak of this war, Vance was not a typical hardliner. He has repeatedly expressed reservations about launching large-scale military actions and has remained skeptical of the optimistic assessments given by Washington and some allies before the conflict, which touted the war as "controllable and quick to win." According to reports from Axios and the Planet Daily, Vance had raised questions about intelligence and assessments even before the escalation of the conflict, which aligns closely with his traditionally wary stance towards military expansion overseas.

For a long time, Vance has been known in American politics for his opposition to endless overseas conflicts. He dislikes "unending wars" and emphasizes that the US should withdraw resources from prolonged foreign wars for domestic development. This consistent stance over the years has shaped his personal image in both domestic and international contexts: he is neither a traditional isolationist nor a security hawk eager to engage in war, but rather a skeptic particularly sensitive to the costs and consequences of military intervention.

It is precisely for this reason that when the risk of the situation spiraling out of control increased, media outlets like Axios and the Planet Daily began to identify Vance as a "potential chief negotiator for the US." The reports indicate that among the existing government officials, he holds a high position while maintaining a certain distance from the traditional security team, enabling him to represent Washington's willingness to negotiate without fully endorsing the existing hardline approach. For the White House, pushing the vice president to the forefront is itself a signal: this is not a routine "communication," but an indication of the US's serious attitude in searching for a political solution.

Internally, Vance has been assigned a dual role of being "understood by adversaries while still representing the core power of the US." On one hand, the White House needs his personal image to add credibility to diplomatic efforts, and on the other hand, it hopes to convey through him that the US has not made a strategic "softening," but is merely willing to keep options open to avoid larger-scale conflicts.

Multiple Calls and Silent Messaging: Vance's Wartime Discourse Power

From the publicly available information, Vance has already had multiple conversations with Netanyahu. The reports did not reveal the specific content and duration of each conversation, but it is certain that the frequency of the calls is relatively high, with the main focus of discussion revolving around the direction of the war, Israel's security bottom line, and under what conditions de-escalation of the conflict could be considered. Vance has explicitly reserved his opinions regarding Israel's pre-war excessive optimism in these conversations, leaving room for discussions on "what kind of ceasefire would not be seen as a sign of weakness."

At the same time, the direct communication between the US and Iran is still in the indirect communication phase. According to Axios and the Planet Daily's description, neither side has entered into any formally defined negotiation setting; instead, they are communicating through multiple channels, testing each other's limits. In this complex backchannel, Vance's role is more like a "relay station": he needs to understand the truly untouchable red lines from Israel, while also internally coordinating to transform this information into signals that can be understood by Tehran, which are then delivered through a professional team via indirect channels.

It is important to emphasize that there is currently no publicly available negotiation timeline, nor any credible channel that confirms that negotiations have made "substantial progress." Both the White House and regional parties have maintained a high degree of restraint in revealing details, further indicating that everything is still in a testing phase and not yet at a stage where conditions can be negotiated or texts can be drafted. Any interpretation of these backchannel communications as "a ceasefire is imminent" is an overstatement of the existing information.

From a practical operational perspective, what Vance and his team are currently doing is more akin to willingness testing and bottom line probing: confirming the conditions under which parties are willing to sit down and which issues absolutely cannot be included in any text. This preliminary work is fraught with instability; once the internal political winds shift for any party, the window may close at any time.

A Vice President Perceived by Iran as a Dialogue Partner

Within the White House, some sources believe that it is precisely because of Vance's long-standing opposition to endless overseas conflicts that, combined with his "new face" status within the governmental structure, he is viewed by Tehran as having greater potential for dialogue than traditional hawkish officials. Some officials have stated to the media that Vance's qualifications and record make it easier for Iran to perceive him as a representative who is "open to discussion but not yet completely bound by the logic of war."

The "relatively non-hawkish" label adds a layer of buffer to the credibility of the representatives from Tehran's perspective. For a regime that has long navigated competition with America's security hardliners, the ability to trust that dialogue opponents have the leeway to "take a step back" is crucial. Vance's past cautious or skeptical stance toward war distinguishes him from traditional security hawkish officials, and this difference is seen as a potential diplomatic leverage.

It should be noted that claims suggesting "Iran prefers Vance to lead negotiations" currently primarily stem from a single source and are still in a verification pending state. Research briefs have also clearly warned that this type of information lacks multi-source confirmation and should not be taken as Iran's official position or internal consensus. In the absence of more public signals, a more prudent interpretation is that while Iran is not opposed to Vance's personal portrayal, and may even be relatively accepting, this does not equate to any substantial commitments regarding negotiation frameworks or ceasefire conditions.

This also reflects a structural tension: there is no inherent consistency between Vance's personal image and the overall hardline tone of US policy towards Iran. He needs to utilize his "non-hawkish" label to create negotiation space without deviating from "upholding US security commitments and promises to allies." This delicate balance means that even if he gains some trust in Tehran, he must constantly face scrutiny and accountability from within Washington.

Under Currents of Resistance from Israel's Hardline Faction Against Vance

In contrast to Iran's cautious acceptance, Vance finds it difficult to be seen as a "natural ally" by the hardline faction in Israel. His restrained attitude presents a structural conflict with the internal warmongers and the political forces that have long adhered to a hardline security logic in Israel. For many Israeli security elites, any "ceasefire initiative" from Washington could be interpreted as a potential constraint on their deterrence and security strategy.

One of Vance's advisors revealed to the media that "there are some within Israel attempting to marginalize this vice president, viewed as 'not tough enough'". However, this statement itself is also labeled as pending verification and lacks sufficient public evidence to support its specific mechanisms and operational methods. Due to principles of information transparency and caution, this can currently only be viewed as a description of the atmosphere and tendencies, rather than a deduction that Israel has developed a systematic strategy to "marginalize Vance."

From a decision-making perspective, Israeli leaders will prioritize whether Vance's leadership in the peace mediation will restrict their activity in the battlefield and at the negotiating table. If the ceasefire process is deemed to weaken pressure on the enemy or impose political costs on domestic hardline voter groups, then any mediation led by the US vice president will naturally be met with caution or even opposition. This caution may not necessarily manifest as public conflict but is more likely to lead to procrastination on proposals or maintaining ambiguity on key agendas.

Therefore, we can clearly see the strategic divergence between Washington and Jerusalem regarding war and peace: the US is concerned about the conflict escalating to an uncontrollable state, emphasizing the need to "apply brakes" through political means; Israel, on the other hand, tends to maintain high pressure until the security threats are subjectively deemed "sufficiently downgraded." Vance is placed in the middle of this fissure, but there is still insufficient public information to indicate that this divergence has evolved into a specific, quantifiable institutional game.

The Power Chessboard within the White House and Vance's Diplomatic Space

In the context of the US system, positioning the vice president rather than the traditional national security team at the forefront of the US-Iran war diplomatic efforts carries a strong implication of power and institutional significance. Traditionally, similar crises are often led by the Secretary of State, National Security Advisor, and other professional entities, while the White House's choice to highlight Vance is not only a political arrangement shaping a negotiation image externally but also a signal of reallocating external discourse power internally.

Vance has limited domestic political experience but has gained significant speaking rights on issues related to great wars and ceasefires, which brings him both exposure and considerable risk. Should the peace attempt falter or be interpreted as heavy pressure on allies, he may become the primary target for criticism from all sides; conversely, if the war escalates and the negotiations collapse, he may find it difficult to completely sever ties to this diplomatic effort.

His "anti-war inclination" now presents a double-edged sword: on one hand, it naturally positions him as a potential interface for domestic anti-war sentiment and international society, making it easier for him to resonate when making public statements; on the other hand, it could be scrutinized by the security hawks within Washington—questioning whether such a vice president might show weakness at critical moments or send misleading signals to allies. This internal questioning has not yet fully surfaced but remains as a potential variable in the decision-making backdrop.

From a longer-term perspective, Vance's current role is both a peace signal released externally and a test piece in the internal adjustment of power structures in the US. By granting the vice president more direct diplomatic functions, the White House has, to some extent, broken the existing bureaucratic division, testing a more centralized and personalized crisis management model; the outcome of this endeavor in terms of reinforcing or undermining institutional stability remains uncertain.

A Fragile Window of Hope and Risk for Ceasefire

In summary, Vance is currently in a unique yet extremely fragile intermediary position between the indirect communication channels concerning the US and Iran and the complex US-Israel relationship. He is neither a traditional security hardliner nor a technical bureaucrat completely detached from domestic politics, but a political figure imbued with a distinct personal image, pushed to the forefront by the system. This setting has granted him a certain degree of dialogue space, but also makes him more susceptible to the converging pressures from multiple parties.

The only confirmed fact at present is that the US and Iran are communicating through indirect channels, with Vance playing an important role in that process; the White House is attempting to release serious negotiation signals through him. Yet, there is no publicly available negotiation schedule, nor is there a clear statement from Iran regarding the negotiation content and framework. In such an information environment, any narrative about "the ceasefire entering a substantive phase" or "major progress to be announced soon" belongs to an excessive extension of limited facts.

In the upcoming period, whether parties can truly make use of this window opened by Vance to prevent further escalation of conflict will depend on several key variables: Iran's internal reassessment of risks and rewards, Israel's hardline faction's tolerance of external pressures, and the domestic political oscillation in Washington between war and peace. Should any of these links undergo drastic changes, this window may rapidly constrict or even close completely.

For external observers, a more cautious approach is to continuously monitor subsequent public signals and multi-source reports: for example, the subtle changes in language from various parties, the adjustments in attitudes towards indirect communications, rather than prematurely betting on the extreme paths of "peace is certain" or "war is destined to escalate." At the moment when Vance bets on peace, what truly needs to be seen may not be a heroic turn of events, but those fleeting, yet potentially trajectory-altering small windows within the structural game.
