[Video below.] Former White House national security adviser John Bolton said Sunday that the United States has yet to complete its objectives in the ongoing conflict with Iran, even as the fighting has now stretched beyond two months.

Appearing on NewsNation’s “The Hill Sunday,” Bolton argued that while the U.S. holds a strong position militarily, its broader goals remain unfulfilled. “Well, it’s anybody’s guess at this point, I think the United States holds a great advantage here, but it hasn’t finished the job that was started,” Bolton told host Chris Stirewalt.

He went on to outline what he believes would constitute a decisive outcome. “My definition of finishing the job is ousting the regime in Tehran, but there are steps less than that that [President] Trump could take, and I’m a little surprised that he hasn’t done it,” he added.

Bolton’s comments came after President Trump indicated last week that he was dissatisfied with the current situation between Washington and Tehran, particularly as nuclear negotiations between the two sides have stalled.

“We’ve already won, but I want to win by a bigger margin,” Trump said during an interview with Newsmax’s Greta Van Susteren.

He continued by emphasizing that, in his view, the damage inflicted on Iran has been extensive, but still insufficient. “We’ve destroyed everything. If we leave right now, it will take them 20 years to rebuild, if they ever could rebuild, but it’s actually not good enough,” he added. “We have to have guarantees they will never have a nuclear weapon.”

Iranian officials, for their part, have said they are reviewing Washington’s response to a recent proposal aimed at ending the war, while stressing that the discussions are not centered on nuclear issues.

Meanwhile, tensions in the region remain high. On Sunday, a cargo vessel traveling near the Strait of Hormuz reported coming under attack by several small boats, according to the British military’s United Kingdom Maritime Trade Operations center. The incident is one of at least two dozen similar attacks reported in the area since the conflict began.

Public opinion in the United States appears divided, with a recent Washington Post-ABC News-Ipsos poll showing that a majority of Americans disapprove of the military action. According to the survey, 61 percent of respondents said they believe the Trump administration made the wrong decision in launching the operation against Iran.

The ongoing conflict has also had economic repercussions. The Strait of Hormuz, a critical route for global oil shipments, has remained closed throughout much of the fighting. As a result, fuel prices have climbed significantly, with AAA reporting that the national average for a gallon of gas has risen to about $4.45, compared to $3.17 at the same time last year.
