**The United States did not declare war on Iran and the country kept its nuclear program active.**

Mojtaba Khamenei remained Iran's supreme leader through 2026. Iran also did not acquire nuclear weapons before 2027.

Reza Pahlavi neither assumed the Iranian leadership nor entered the country by the end of 2026. The political hierarchy therefore experienced no change throughout the year. Existing institutions continued under the established leadership.

Iran refrained from surrendering its enriched uranium stockpile by the December deadline. It also maintained its uranium enrichment program beyond the same cutoff. The continuation signaled no shift in nuclear policy.

The Iranian government did not implement fees for transiting vessels in the Strait of Hormuz by the October deadline. Shipping costs in the strategic waterway remained unchanged. No new revenue mechanism was introduced.

The year concluded without a change in Iran's supreme leadership. The United States maintained a non-war stance toward Tehran. Iran's nuclear and maritime policies continued unchanged.

## Analysis

The persistence of Khamenei's authority meant that Iran's domestic power structure stayed intact, limiting opportunities for reform or policy redirection. Any internal opposition remained constrained by the established clerical hierarchy, though the level of dissent is not publicly quantified.

The United States' decision not to declare war avoided an immediate escalation that could have destabilized the region. While the absence of formal conflict reduced short-term military risk, underlying geopolitical tensions between Washington and Tehran persisted, leaving future policy options open.

Continuing uranium enrichment and retaining the enriched stockpile kept Iran's nuclear pathway unchanged, influencing ongoing non-proliferation discussions. The lack of a surrender or enrichment halt suggests that diplomatic leverage tied to nuclear concessions remained unavailable, but the prospect of future negotiations is still uncertain.

This decision may reflect strategic calculations about trade flow and regional influence, yet it leaves open whether Tehran Will pursue alternative economic measures in the coming years.
