Ahead of his trip to China, President Donald Trump gave conflicting answers when asked on Tuesday if Beijing should intervene to help end the war with Iran.

"I don't think we need any help with Iran," he said at first. Minutes later, when Trump was asked if Chinese President Xi Jinping was the person who could revive the ceasefire, the president said he would like whatever help Xi can offer.

But, when pressed on Xi's possible help, Trump again said the U.S. did not need assistance. "They're defeated militarily, and they'll either do the right thing or we'll finish the job," Trump said.

Moments later, Trump added that he "wouldn't say Iran" is one of the topics he plans to discuss with Xi because the U.S. has it "under control."

"We're either going to make a deal or they're going to be decimated, one way or the other," Trump said.

Trump again dismissed economic concerns related to the ongoing war, suggesting inflation would fall 1.5% after the war ends amid what he predicted would be a "gusher of oil."

"And one way the other, it's going to work out very well. Going to work out very well. I think you have so much oil, you're going to have a gusher of oil like you've never had before," Trump said, once again stressing that he thought oil prices would have risen higher.

"And as soon as this war is over, which will not be long, you're going to see oil prices drop, and you're going to see a stock market, which is already at the highest point in history, go through the roof. You're going to see the golden age of America, frankly, and you're seeing it now," Trump said.

Asked about the progress of negotiations with Tehran, Trump said, "Well, we're going to see what happens. We're only making a good deal."

"But I believe that one way or the other, it's going to be very good for the American people, and I think actually very good for the Iranian people," Trump said.

The Iran war is estimated to have cost $29 billion, acting Pentagon comptroller Jules W. Hurst III told lawmakers Tuesday morning during a House Appropriations hearing.

Two weeks ago, Hurst testified it was $25 billion, much of which was attributed to munitions costs.

Hurst said the updated number comes after accounting for, "replacement of equipment costs and also just general operational costs keep people in theater."

Rep. Pete Aguilar, D-Calif., asked Secretary of Defense Pete Hegseth when Congress would get a more detailed accounting for war costs.

“When it's relevant and required, we will share it,” Hegseth responded.

The Israel Defense Forces said in a post to X on Tuesday that it hit 45 alleged Hezbollah targets in southern Lebanon over the past day.

The IDF claimed that its targets included command posts, observation posts, assembly points, warehouses and other buildings it alleged were being used by Hezbollah forces in the area.

Hezbollah on Tuesday claimed a rocket attack on Israeli forces deployed in southern Lebanon.

Lebanon's Ministry of Public Health said on Monday that at least 2,869 people have been killed and 8,730 people wounded in Lebanon since cross-border fighting resumed on March 2.

Ebrahim Rezaei, a member of the Iranian parliament and the spokesperson for the body's National Security and Foreign Policy Commission, suggested in a post to X on Tuesday that renewed attacks on the country may prompt lawmakers to consider a higher level of uranium enrichment.

"One of Iran's options in the event of another attack could be 90% enrichment," Rezaei wrote in a post to X. "We will review it in the parliament."

Weapons-grade uranium -- enriched to a high enough level to use as fuel in a nuclear weapon -- is generally considered to require enrichment of 90% and above. Iran has amassed a stockpile of uranium enriched to 60%, the fate of which is a key issue in ongoing peace talks.

The U.S. has estimated that Iran amassed around 1,000 pounds of 60% enriched uranium. President Donald Trump has said that the stockpile was buried underground during the U.S. strikes on Iran's nuclear facilities last year, saying this weekend that the site is "very well surveilled."

President Donald Trump told Fox News journalist John Roberts he is considering restarting Project Freedom, but noted that the U.S. Navy’s role in allegedly “guiding” ships through the Strait of Hormuz would “only be a piece of it."

Further details of the president's plans with the operation were not immediately available.

Project Freedom went into effect exactly one week ago before Trump abruptly paused it Tuesday evening.

According to Fox News, Trump expressed confidence in Iran complying with his demands, saying “they’re going to fold.” On Sunday, Trump blasted Iran's response to the U.S. proposal, calling it "totally unacceptable."

Asked whether he wishes to negotiate with a new round of leaders in Iran, Trump told Fox News, "I will deal with them until they make a deal.”

Trump has repeatedly criticized Iran’s leadership, saying they’re disjointed and not able to communicate with each other. In recent weeks, the president has also suggested that he doesn’t need to make a deal with Iran at all.

Trump also reportedly told Fox News that Iranian negotiators said Iran does not have the technology to retrieve their nuclear dust and that the U.S. must go into Iran to obtain it.
