Assault or diplomacy: Washington’s deliberate mixed signals to Tehran

As the United States naval forces assemble in the Gulf even as Washington acknowledges ongoing talks with Tehran, the US appears to be pursuing a carefully calibrated but inherently risky strategy.

By pairing visible military pressure with diplomatic outreach, Washington seeks to coerce Iran into concessions while avoiding commitment to a wider conflict. This dual-track posture underscores an effort to maximize diplomatic leverage while preserving flexibility. This, however, exposes the limits of signaling when strategic intent remains ambiguous.

At its core, the current US approach relies on a familiar logic. The presence of an aircraft carrier group and accompanying assets communicates readiness and deterrence, while diplomatic engagement suggests that escalation is not an end in itself. Such a strategy assumes that the credible threat of force can shape adversary behavior more effectively than force alone. However, credibility depends not only on military capability, but on clarity of political purpose, something that remains indistinct in the present moment.

The absence of a clearly articulated endgame complicates Washington's signaling. It is not evident whether the US seeks discrete behavioral changes from Tehran, a longer-term posture of containment or a broader recalibration of the bilateral relationship.

This ambiguity may offer short-term leverage in dealings with Iran, but it also creates interpretive risks. The signals intended to influence Tehran's calculations do not exist in a vacuum; they are observed, interpreted and acted upon by multiple audiences.

The recent protests inside Iran illustrate this dynamic, although indirectly. While driven initially by longstanding economic and social grievances, they unfolded amid heightened US warnings to Tehran and expressions of diplomatic and political pressure. As geopolitical analyst and Asia Times columnist Bahauddin Foizee has noted , the US statements were viewed through the lens of President Donald Trump's past record of translating stated intentions into action, most notably Nicolas Maduro's capture and high-profile assassinations, lending additional weight to Washington's messaging even in the absence of explicit commitments.

This episode highlights a broader challenge inherent in coercive diplomacy. Military deployments and diplomatic engagements intended to deter state behavior can simultaneously generate expectations beyond their intended scope. Without clear boundaries, pressure risks being misread either as a prelude to action or as a hollow and ambitionless decoy designed merely to extract leverage.

For Washington, credibility is often framed in terms of resolve and willingness to act. At the same time, credibility also depends on alignment, between stated intentions and strategy, pressure and restraint, means and objectives. A posture that combines military readiness with diplomatic openness can succeed only if its underlying purpose is clearly understood by both adversaries and partners.

But without such clarity, the US risks sending contradictory messages, signaling on deterrence toward Iran while leaving open questions about what, precisely, deterrence is meant to achieve. In that space between diplomacy and the prospect of conflict, both tools can lose effectiveness.

The central issue, therefore, is not whether Washington can apply pressure on Iran, but whether that pressure is embedded within a coherent political strategy.

For policymakers seeking to manage escalation and preserve diplomatic options, the effectiveness of the current approach will depend less on the scale of US deployments in the Gulf than on the clarity and consistency of the strategy guiding them.
