Analysis: The US "Maximum Pressure" Strategy and the Geopolitics of Iran

While the stringent rhetoric from the United States toward Iran aligns with historical foreign policy postures, a strategic examination suggests these statements serve a dual purpose. They function as a mechanism to gauge both domestic public sentiment and international responses, while signaling a potential escalation in the US "Maximum Pressure" campaign against Tehran.

1. The 2018 Policy Shift: Escalation of Tensions

In 2018, relations between the United States and Iran reached a critical juncture following Washington's unilateral withdrawal from the Joint Comprehensive Plan of Action (JCPOA). This decision marked a significant divergence from the other signatories—Russia, China, the United Kingdom, France, Germany, and Iran—who advocated for the preservation of the multilateral framework.

The withdrawal was accompanied by the reimposition of comprehensive economic sanctions. The US government restricted American corporate engagement with Iran and instituted secondary sanctions targeting global entities. Under these measures, third-party nations continuing to import Iranian oil faced severe economic penalties and exclusion from the US financial system.

Concurrently, key US lawmakers, including Senator Lindsey Graham, articulated a firm stance, identifying Iran’s nuclear ambitions and regional activities as a primary challenge to US interests. The underlying message from Washington indicated a readiness to utilize all available economic and diplomatic levers to alter the Iranian government's strategic calculus.

2. Diplomatic Rhetoric and Strategic Posturing

As policy shifted, diplomatic rhetoric intensified on both sides. The US executive branch issued a stern warning to Tehran against directing threats toward the US, stating that such actions would result in "consequences that few nations throughout history have suffered before."

In response, Iranian President Hassan Rouhani adopted a resolute counter-posture, stating:

"Mr. Trump, do not play with the lion's tail, because you will regret it."

Rouhani cautioned that US military intervention would trigger widespread regional instability and asserted that Iran would not yield to external coercion. Furthermore, Tehran introduced a strategic counter-threat: if Iranian oil exports were completely blocked, the stability of oil exports from the broader Persian Gulf region would be compromised. Tehran also signaled its capacity to disrupt transit through the Strait of Hormuz—a vital global energy chokepoint—framing the crisis as a direct consequence of US unilateralism.

3. Analyzing the Strategy Through Two Analytical Lenses

To comprehensively understand the dynamics of this period, the US posture can be examined through two distinct analytical frameworks: Rhetorical Continuity and Strategic Coercion.

📌 Perspective 1: Rhetorical Continuity and Domestic Signaling

From this viewpoint, the administration's posture is largely consistent with long-standing US foreign policy narratives. Designating Iran as a primary regional adversary and citing concerns over its nuclear program, proxy networks, and domestic governance are recurring themes in Washington.

The primary structural change was the formal exit from the JCPOA, which the administration characterized as fundamentally flawed. Viewed through this lens, the heightened rhetoric serves primarily as a political signal to project strength to the domestic electorate and reinforce "America First" policy commitments, without necessarily indicating an intent to initiate kinetic military action.

📌 Perspective 2: Strategic Coercion and the "Maximum Pressure" Campaign

Viewed through a strategic lens, the combination of rhetoric and sanctions represents a calculated effort to apply maximum leverage on Tehran, testing the thresholds of both the international community and the Iranian state.

Historically, US policy has sought to curtail Iran's regional influence. While the Obama administration pursued diplomatic engagement via the JCPOA, the foundational objective of limiting Iran's strategic reach remained unchanged. Under the subsequent administration, this objective was pursued through aggressive economic statecraft, which intersected with several internal variables within Iran:

  • Domestic Unrest: Between late 2017 and early 2018, significant public protests erupted across Iran, originating in Mashhad before spreading nationwide. Driven primarily by economic grievances—such as high inflation and unemployment—the demonstrations eventually led to civil friction and property damage. The government's subsequent security crackdown highlighted internal domestic vulnerabilities. Notably, this initial wave of unrest preceded the formal US withdrawal from the nuclear deal.
  • Economic Compounding: By mid-2018, a second wave of protests emerged, fueled by identical economic challenges but exacerbated by the anticipation of renewed US sanctions. While the Iranian economy has historically demonstrated resilience against external pressures, the comprehensive nature of the new measures threatened to deepen economic contraction, impacting employment and currency stability.
  • Currency Depreciation: Concurrently, the Iranian Rial experienced severe depreciation on the open market, dropping from 90,000 to over 110,000 Rials per US dollar within a single month. Iranian officials characterized this volatility as a "psychological and economic war" aimed at undermining public confidence in the national economy.

From this perspective, US rhetoric functioned as a core component of economic statecraft. The heightened geopolitical uncertainty accelerated capital flight and compounded internal economic challenges, thereby applying indirect pressure on the Iranian state structure.

4. Potential Trajectories and Regional Security

With other geopolitical flashpoints showing varying degrees of stabilization, Iran remained the focal point of US national security strategy. Operating under a unilateral framework, the US administration demonstrated a willingness to operate outside traditional multilateral consensus, diverging from the International Atomic Energy Agency (IAEA) and European allies who had verified Iran's compliance with the JCPOA.

Geopolitical analysts point to several potential trajectories resulting from this strategy:

  • Targeted Military Action: The potential for tactical airstrikes remains a contingency in response to specific security triggers, such as accelerated uranium enrichment or regional proxy friction, mirroring previous conventional interventions in the Middle East.
  • Internal Political Dynamics and Regional Proxies: A strategy focused on compounding economic pressure to induce political shifts from within, or altering the balance of power among regional proxy groups—a path that carries the inherent risk of prolonged regional instability, similar to the systemic collapses observed elsewhere in the region.

Conclusion

Viewed strategically, the convergence of external economic containment and internal economic vulnerabilities represents a calculated approach to altering the regional balance of power. The objective is to create a synergistic effect where sanctions and domestic economic friction compel a shift in the Iranian government's strategic calculations and regional policies.

Even if the strategy does not lead to immediate political transformation, significantly degrading Iran's economic capacity and regional reach is viewed in Washington as a strategic success. Ultimately, the trajectory of this policy depends on whether diplomatic off-ramps can be established, or if the strategic imperative to neutralize the perceived threat leads to further escalation. In the broader context of US long-term strategic planning, Iran remains a primary systemic challenge.
