Trump Eyes ‘New Golden Age' for US Nuclear Umbrella on China's Doorstep
The United States aims to pursue a "new golden age" in its relationship with Japan as the two countries recently discussed America's extended deterrence—commonly known as the nuclear umbrella—amid China's military buildup, a State Department official told Newsweek.
Newsweek has contacted the Chinese defense and foreign ministries for comment by email.
The U.S. has committed to defending Japan through extended deterrence, which refers to the pledge to deter and respond to nuclear and non-nuclear threats against allies and partners, including, if necessary, through the use of nuclear weapons. Over 30 countries are protected by America's nuclear umbrella, a recent Congressional Research Service (CRS) report stated.
According to the Pentagon, China continues its rapid nuclear expansion and is estimated to possess over 600 warheads in its nuclear arsenal—making it the third largest in the world. The Chinese military has significantly expanded its medium-range ballistic missile fleet, which is capable of striking Japan as well as U.S. military bases located there.
The Extended Deterrence Dialogue was held from June 5-6 at Barksdale Air Force Base in Louisiana, the U.S. State Department and the Japanese Foreign Ministry said on Monday. The bilateral dialogue was hosted by the U.S. Air Force Global Strike Command.
The U.S. side was represented by officials from the State Department and the Pentagon, while the Japanese delegation included officials from Japan's foreign and defense ministries, as well as the Japanese Embassy in Washington, D.C., according to the command.
Established in 2010, the bilateral discussion allows both governments to address strategic deterrence, including nuclear and missile defense policy, Japan's foreign ministry said.
"Our tailored dialogues with allies in the Euro-Atlantic and Indo-Pacific have become deeper and broader," the U.S. Air Force Global Strike Command told Newsweek, adding that these efforts strengthen allied understanding of U.S. nuclear deterrence posture and capabilities.
This iteration, which was the first held under the second Trump administration, included a visit to the U.S. Air Force Global Strike Command's training facilities. Officially released photos show the Japanese delegation taking a close look at America's B-52H strategic bomber fleet.
The U.S. Air Force operates 76 B-52H bombers, according to the Federation of American Scientists, 46 of which are capable of carrying nuclear cruise missiles. This type of bomber was deployed to Guam—a U.S. military hub in the western Pacific Ocean—last month.
Since 2022, this dialogue between Washington and Tokyo has taken place at key locations of the U.S. nuclear triad, which comprises strategic bombers, ballistic missile submarines, and intercontinental ballistic missiles (ICBMs), the U.S. Air Force Global Strike Command added.
Last year, American and Japanese officials met at Francis E. Warren Air Force Base in Wyoming, where the Japanese delegation visited the U.S. intercontinental ballistic missile (ICBM) mission. The base operates Minuteman III ICBMs on full alert around the clock.
A U.S. State Department official told Newsweek: "This [Extended Deterrence Dialogue] advanced President Trump's determination to pursue a new golden age for U.S.-Japan relations and to further enhance U.S. extended deterrence."
The U.S. Air Force Global Strike Command told Newsweek: "The United States does not face the challenging international environment alone. Our network of allies and partners in the Euro-Atlantic and the Indo-Pacific is an asymmetric advantage that our adversaries can never hope to match."
The U.S. is also likely to enhance its extended deterrence to South Korea—another treaty ally in Northeast Asia—in order to better counter North Korea's nuclear and missile threats.

Trump warns of more attacks; lauds ‘spectacular military success' on Iran nuclear sites
President Trump on Saturday declared U.S. strikes on Iran's key nuclear facilities were a 'spectacular military success,' but warned in an address to the nation that he could order further action if Tehran does not agree to a satisfactory peace agreement. 'Our objective was the destruction of Iran's nuclear enrichment capacity and a stop to the nuclear threat posed by the world's number one state sponsor of terror,' Trump said in remarks from the Cross Hall at the White House. 'Tonight, I can report to the world that the strikes were a spectacular military success.' The president had announced hours earlier on Truth Social that the U.S. had bombed three Iranian nuclear facilities: Fordow, Natanz, and Esfahan. Trump, who was joined by Vice President Vance, Secretary of State Marco Rubio and Defense Secretary Pete Hegseth for his remarks, warned that Saturday's strikes could be the first in a wave of actions against Iran, which has been locked in conflict with Israel for nearly two weeks. Trump delivered his address from the doorway of the East Room, with the grand foyer in the background, the same place former President Obama delivered his address to the nation announcing the killing of Osama Bin Laden. 'This cannot continue. There will be either peace or there will be tragedy for Iran far greater than we have witnessed over the last eight days,' Trump said. 'Remember, there are many targets left. Tonight's was the most difficult of them all, by far, and perhaps the most lethal. But if peace does not come quickly we will go after those other targets with precision, speed and skill.' DEVELOPING

US Attacks Three Main Nuclear Sites in Iran, Widening Conflict
(Bloomberg) — US President Donald Trump said American bombers struck Iran's three main nuclear sites, pulling the US directly into the country's conflict despite his longtime promises to avoid new wars.

Natanz and Isfahan, two other sites, were also struck. The president called the operation 'very successful,' adding that the aircraft involved had exited Iranian air space. 'NOW IS THE TIME FOR PEACE!' he wrote on Truth Social. Trump addressed the nation at 10 p.m. Washington time at the White House. Israel was notified in advance of the strikes, according to a person familiar with the matter who asked not to be identified discussing private deliberations. Trump spoke to Israeli Prime Minister Benjamin Netanyahu after the strikes, a senior White House official said. The move marks an extraordinary escalation by the president in the week since Israel began airstrikes across Iran and amounts to the most serious foreign-policy decision of his two terms so far. It goes against the advice of US allies in Europe as well as the United Nations' International Atomic Energy Agency, which has repeatedly warned that nuclear facilities must never be attacked given the potential threat to nuclear safety — not to mention radiation leaks.

Iran has said it doesn't want a nuclear bomb, and Trump's own intelligence agencies had assessed recently it still hadn't committed to developing such a weapon. Trump, however, had dismissed those findings and had declined to rule out joining the Israeli strikes, which had also killed several prominent Iranian military officials and nuclear scientists. The US strikes could immediately open American assets in the Middle East to attack since Iran had warned it would retaliate if Trump ordered an attack. Trump's combative language in the last couple of days had also triggered new threats from the Iran-backed Houthi rebels in Yemen and led Iranian officials to call the US Israel's 'partner in crime.' Iran's retaliation could also come in the form of cyber attacks against American or Israeli interests by hackers linked to the regime in Tehran. Earlier Saturday, the State Department said the US had begun evacuating US citizens from Israel. The agency organized two flights to Athens from Tel Aviv with about 70 US citizens, family member and permanent residents, it said. 'I hope that the Iranians are measured in their response but there will be a response — this is an act of war by the United States against a foreign country, which has not attacked us lately,' said Barbara Slavin, a distinguished fellow at the Stimson Center. 'Americans are at risk all over the Middle East, all over the world.' Iran's official Islamic Republic News Agency reported that authorities in Isfahan confirmed multiple simultaneous explosions in Natanz and Isfahan early Sunday, describing them as 'aggressions' near the two nuclear facilities. Fears of an impending strike had eased after Trump's team said on Thursday he would make a decision within two weeks. On Friday, the foreign ministers of France, Germany and the UK had met with Iranian officials Geneva in a bid to prevent a US attack. The continued fighting has evoked fears of a regional conflict that results in massive civilian casualties, and disrupts the flow of energy and other trade through the region. About a fifth of the world's daily oil supply goes through the Strait of Hormuz, which lies between Iran and its Gulf Arab neighbors such as Saudi Arabia. For days, Trump had faced conflicting advice from his supporters, after he campaigned for president on promises to keep the US out of foreign wars, pointing to American involvement in Afghanistan and Iraq. MAGA allies including longtime Trump supporter Steve Bannon, have warned against any US intervention, insisting this is Israel's fight to finish. Other Republicans had been urging Trump to join the fight against Iran, arguing that Tehran was more vulnerable after days of air strikes by Israel, and there was an opportunity to deliver on the president's long insistence the regime cannot be allowed to have a nuclear weapon. Trump and his advisers had suggested in recent days that any strike would be limited. Trump briefed Senate Majority Leader John Thune and House Speaker Mike Johnson, according to people familiar with the matter. 'This is not the start of a forever war,' Senator Jim Risch, the Idaho Republican and chairman of the Senate Foreign Relations Committee, said on X. 'There will not be American boots on the ground in Iran. This was a precise, limited strike, which was necessary and by all accounts was very successful.' Energy experts have raised concerns that crude flows in the region could be imperiled if Iran and its proxies retaliate in response to a US attack. Fears have focused on the Strait of Hormuz, a narrow waterway at the mouth of the Persian Gulf that is a key transit point for 26% of the world's oil trade. Houthis have previously disrupted Red Sea shipping, with attacks on ships in the Bab el Mandeb strait forcing vessels to reroute around Africa. A broader attack — including potentially planting naval mines — on the Strait of Hormuz could have even wider consequences, since it's such a vital artery for the region's oil and gas output. What If Iran Tries to Close the Strait of Hormuz?: QuickTake US ally Israel had launched a surprise attack on Iran on June 13, saying the imminent threat of the regime in Tehran securing nuclear weapons had to be neutralized. Iran's military infrastructure was seriously damaged and a number of its top generals and atomic scientists were killed. But Israel lacked the heavy bombs and B-2 stealth jets believed to be required to destroy nuclear sites buried deep underground. Tehran had responded to Israel's strikes by firing waves of ballistic missiles and drones, breaching aerial defenses, striking several cities and causing unprecedented damage. But the number of projectiles launched by Iran dropped markedly after the first few days of the conflict, raising questions about the number of missiles left in its arsenal and its ability to launch them. 'Iran is going to be facing a real dilemma, because they've already been dramatically weakened,' said Dennis Ross, who served as President Bill Clinton's Middle East envoy and is now a fellow at the Washington Institute for Near East Policy. 'They will try to do something to show they didn't just capitulate or submit, but they have their own interest in trying to limit this.' —With assistance from Natalia Drozdiak, Eric Martin, Courtney McBride, Erik Wasson and Steven T.
