The United States has suspended its airstrikes on Iran after nearly two weeks of escalating military operations, while diplomatic efforts have intensified in an attempt to prevent the conflict from returning to full-scale war.

It remains uncertain, however, whether Washington and Tehran are moving toward a lasting breakthrough as the conflict approaches its fifth month on Tuesday.

President Donald Trump has sent mixed signals, warning that further military action remains an option while also saying negotiations with Iran are continuing. He has dismissed concerns that rising fuel prices linked to the conflict could hurt Republicans in November's midterm elections. 

The situation is further complicated by Israeli Prime Minister Benjamin Netanyahu's planned visit to Washington next week. Israel, which joined the United States in launching military operations against Iran on Feb. 28, has so far stayed out of the latest US strikes following Iran's effective closure of the Strait of Hormuz, through which about one-fifth of global oil supplies normally pass.

Analysts say Israel's absence from the latest phase of the conflict could signal either a desire to avoid widening the war or leave open the possibility of greater military pressure if diplomacy fails.

Regional mediation efforts are continuing, with officials involved in the talks describing the pause in military operations as a positive development that could help reduce tensions.

According to a regional official familiar with the negotiations, discussions are focused on restoring an interim ceasefire while reaching a compromise over shipping through the Strait of Hormuz. The proposal under discussion would allow Iran to oversee vessel transit with fewer restrictions on commercial shipping.

Iran tightened control over the strategic waterway after the conflict began by targeting commercial vessels, contributing to sharp increases in global oil prices. The disruption has raised economic concerns in the United States, where higher fuel costs have become a political issue ahead of the congressional elections.

The US military has expanded its operations in recent weeks, targeting Iran's coastal defenses, transport infrastructure and military positions in an effort to weaken Tehran's ability to threaten shipping in the Gulf.

Analysts believe the military campaign is intended to pressure Iran into returning to negotiations. However, they note that Iran's divided political leadership may complicate diplomatic progress, as some factions could view concessions to Washington as a sign of weakness.

Despite their differences, both countries have strong economic incentives to restore normal shipping through the Strait of Hormuz, although they remain divided over how the waterway should be managed.

Regional tensions remain high despite the pause in direct US-Iran fighting.

Yemen's Iran-backed Houthi rebels said Saturday they launched missiles and drones at Saudi Arabia in response to Saudi airstrikes on the Red Sea port city of Hodeida. The group also claimed it had closed the Bab el-Mandeb Strait, another strategically important shipping route.

Meanwhile, the US military said it continues enforcing its naval blockade of Iranian ports and disabled a Mozambique-flagged vessel in the Gulf of Oman after it allegedly attempted to breach the blockade.

Trump said Friday that Washington has two options: continue military operations or pursue diplomacy.

"We can keep doing exactly what we're doing... or we can negotiate with them, which we're also doing right now," he told reporters.

While saying he does not believe Iran is yet ready to reach an agreement, Trump added that Tehran appears to be taking negotiations more seriously as the conflict continues.

The president also met senior national security advisers on Friday to review US strategy toward Iran, including whether to maintain the current approach or expand military operations. No American airstrikes were reported overnight, ending a streak of 13 consecutive nights of attacks.

Trump insisted he is not rushing to end the conflict because of domestic political considerations, saying his administration's priority is to "do it right" rather than focus on the approaching elections.
