US-Israel War with Iran: A Shifting Landscape
The conflict between the United States, Israel and Iran has entered a complex phase, marked by shifting justifications, evolving objectives, and questions about its ultimate outcome. Following joint U.S.-Israel strikes that killed Iran’s Supreme Leader Ayatollah Ali Khamenei and dozens of senior Iranian officials in late February 2026, the war’s trajectory remains uncertain, even as President Trump signals a potential end may be near.
Origins of the Conflict
The recent escalation began with major combat operations launched by the U.S. And Israel on February 28, 2026, targeting military and government sites within Iran 1. The rationale for these strikes has been a subject of debate, with American and Israeli officials offering differing explanations. President Trump has maintained the necessity of the operations to achieve unspecified U.S. Objectives 2.
Conflicting Perspectives on Justification
Analysts are divided on the justification for the war. Matthew Kroenig argues the action was warranted due to Iran’s long-standing threats to regional and global security, citing its support for terrorism, ballistic missile program, and controversial domestic policies 2. He contends that removing the Islamic Republic, or significantly weakening it, would improve security and the lives of Iranians.
Conversely, Trita Parsi views the war as unnecessary and unjustified, asserting that no imminent threat was presented and that diplomatic options were not exhausted 2. He criticizes the administration for a lack of clear justification and suggests the conflict resembles the lead-up to the 2003 Iraq War.
Escalation and Regional Impact
Since the initial strikes, Iran has retaliated by attacking its neighbors, including those that have attempted to mediate, and targeting shipping lanes 2. This has raised concerns about broader regional instability and the potential for further escalation.
Shifting Objectives and Potential Endings
President Trump has indicated the war may end “soon,” suggesting that the U.S. Military has “practically nothing left” to bomb 3. However, Israeli Defense Minister Israel Katz has stated that the operation will continue indefinitely until its objectives are met 3.
The Trump administration initially stated its goals were to degrade Iran’s nuclear, missile, and drone capabilities, and is claiming to be ahead of schedule in achieving these objectives 3. The possibility of regime change remains a stated, though perhaps diminishing, objective.
Financial Costs
As of March 12, 2026, the war has already cost the United States $11.3 billion in its first six weeks 1.
The Path Forward
The future of the conflict remains uncertain. While President Trump suggests a swift conclusion, differing perspectives between the U.S. And Israel, coupled with Iran’s continued resistance, suggest a prolonged and complex situation. The war’s ultimate impact on regional stability, U.S. Alliances, and the internal dynamics within Iran will be significant and far-reaching.
