Escalating Tensions: Assessing the Growing Risk of US-Iran Conflict

Tensions between the United States and Iran have surged in recent weeks, marked by military movements and heightened rhetoric. While a full-scale war has not yet begun, a confluence of factors suggests the risk of open conflict is increasing, despite ongoing—and thus far unsuccessful—diplomatic efforts.

Key Indicators of Rising Conflict

US Military Deployments

Several recent US military actions signal heightened preparedness for potential conflict. On February 18, 2026, Axios reported that the US is moving closer to a major war with Iran, with little public debate surrounding the potential consequences.

• Tanker Aircraft to Israel: Six US refueling tanker planes have arrived in Israel, bolstering its ability to conduct long-range military operations.
• Non-Essential Embassy Staff Departure: The US government ordered non-essential embassy staff to abandon Israel on February 27, 2026, citing security risks.
• Aircraft Carrier Movement: The largest US aircraft carrier has departed Greece and is sailing towards the Middle East, demonstrating a significant projection of naval power.

Iranian Actions

Iran is also taking steps that suggest preparation for potential conflict.

• Crude Oil Transport: Iran is reportedly accelerating the transport of crude oil to tankers, likely to secure energy exports in the event of disruption.

Diplomatic Efforts and Stalled Negotiations

Despite the escalating tensions, diplomatic efforts to de-escalate the situation are ongoing. Negotiations between the United States and Iran began in April 2025, following a letter from President Donald Trump to Supreme Leader Ali Khamenei, aimed at reaching a nuclear peace agreement. The first round of talks, led by US Special Envoy Steve Witkoff and Iranian Foreign Minister Abbas Araghchi, was held in Oman on April 12, 2025, and initially described as constructive.

A second round of negotiations took place in Geneva on February 27, 2026, but failed to yield a deal. Iranian Foreign Minister Abbas Araghchi warned that any conflict would likely result in a “devastating war.” President Trump has also indicated a willingness to take military action if necessary.

Congressional Response

The US Congress is preparing for a potential war powers resolution vote to block US strikes on Iran. House Democratic Leader Hakeem Jeffries stated that a bipartisan coalition is working to force a vote as soon as next week.

Looking Ahead

The situation remains highly volatile. While diplomatic channels remain open, the increasing military posturing and lack of progress in negotiations suggest the risk of conflict is growing. The coming weeks will be critical in determining whether a path to de-escalation can be found, or whether the region is headed towards a devastating war.
