North Korea has issued a warning to Japan over its upcoming test-fire of a prototype railgun.
The futuristic weapon signals Japan is mulling a preemptive attack on the nuclear-armed country, state media said, adding that this would be a "suicidal act."
Newsweek reached out to the Korean embassy in China and Japan's defense ministry via email for comment.
Why It Matters
Railguns can inflict significant damage without relying on explosives. They use electromagnetic force to fire metal slugs at speeds exceeding Mach 5. The weapons offer a relatively low-cost, effective means of countering threats such as hypersonic missiles, including those fielded.
Official development began in 2016, and the United States ally conducted the first known shipboard test of a railgun in 2023. Another test is planned aboard an experimental warship, this time mounted on a naval turret to simulate real-world combat conditions.
What To Know
An article released Saturday by North Korea's official Korean Central News Agency (KCNA) characterized Japan's ongoing military buildup as part of a plan to establish another "great Japanese empire."
Development of new weapon platforms such as the railgun is "aimed at enhancing and expanding the utility of preemptive attack directly targeting the DPRK [Democratic People's Republic of Korea] and the neighboring countries and thus realizing at any cost the old ambition of the Greater East Asia Co-Prosperity Sphere," KCNA quoted international security analyst Kim Ryo Won as saying, using North Korea's official name.

Framed as a pan-Asian bloc led by Tokyo, the "Greater East Asia Co-Prosperity Sphere" was a concept used by the Empire of Japan to justify its expansion during World War II.
"The reckless military buildup of Japan, a war criminal state, to make a preemptive attack on nuclear weapons states while turning the archipelago into a huge powder magazine will be a suicidal act of dashing toward the second defeat," Kim said.
Japan has been steadily strengthening security ties with the U.S. and South Korea, focusing on the North Korean threat and China's increasing assertiveness.
North Korea claims to have successfully tested an intermediate-range hypersonic missile in January, though South Korean officials have expressed skepticism about its stated capabilities.
Pyongyang has carried out frequent missile tests in violation of United Nations Security Council sanctions and continues to build out its nuclear weapons program. The Kim Jong Un regime insists both are necessary for self-defense, citing "provocations" by the U.S. and its allies.
What People Are Saying
The Japan Maritime Self-Defense Forces, in an April press release: "The Self-Defense Fleet maintains readiness and contributes to the peace and stability of the Indo-Pacific region, not only for the defense of Japan but also for the realization of a 'Free and Open Indo-Pacific' in cooperation with allied and like-minded navies."
What Happens Next
It remains unclear when Japan plans to field its railgun.
China has also been developing a railgun and reportedly conducted a shipboard test last year, though it was said to have failed after the projectile veered off course.
The U.S. Navy abandoned its railgun program in 2021, shifting its focus to other advanced weapons, including hypersonic missiles.

The great poaching: America's brain drain begins
The Trump administration's spending cuts and restrictions on foreign students are triggering a brain drain — and American scientists are panicking. Why it matters: U.S. researchers' fears are coming true. America's science pipeline is drying up, and countries like China are seizing the opportunity to surge ahead. 'This is such a race for being the science powerhouse that you never fully recover,' says Marcia McNutt, president of the National Academy of Sciences. 'You might accelerate back up to 60, but you can't make up for those years when you were at a standstill while the competition was racing ahead.' Driving the news: The National Science Foundation, which funds much of America's fundamental science research, is already doling out grants at its slowest pace in 35 years, The New York Times reports. More cuts to science could come with the "big, beautiful bill." Universities are also watching with bated breath as the administration tries to limit the number of foreign students studying in the U.S.. Harvard is pushing back, but could face a total ban on recruiting internationally. The Trump administration says it will " aggressively revoke" visas for Chinese students studying in "critical fields." By the numbers: While American universities are rescinding offers to incoming PhD students, other countries are recruiting heavily from U.S. labs. The journal Nature analyzed data from its jobs platform to track where scientists are looking for work. In the first few months of the Trump administration, there were jumps in the the number of U.S. applicants looking for jobs in Canada (+41%), Europe (+32%), China (+20%) and other Asian countries (+39%), compared to the same period in 2024. U.S. jobs saw fewer applications from candidates in Canada (–13%) and Europe (–41%). Case in point: France's Aix-Marseille University, which made headlines for earmarking millions of dollars for U.S. scientists, closed its application window after receiving a flood of apps. After American Nobel laureate Ardem Patapoutian's federal grant was frozen, he got an email from China offering 20 years of funding if he relocates his lab, The New York Times' Kate Zernike writes. He declined. 'This is a once-in-a-century brain gain opportunity,' the Australian Strategic Policy Institute wrote in a brief. The other side: The White House argues that its changes to the system will usher in a golden age of science and rebuild public trust. President Trump has also suggested that spots freed up by rejecting international students could be filled by American applicants. But professors say this isn't entirely realistic. "In hard sciences, in astronomy and physics and computer science, for example, there's no way you would fill that hole with local applicants of comparable quality," says Chris Impey, an astronomer at the University of Arizona. What to watch: 'The optimistic part of all of us thinks science is strong enough to outlast one administration, and for a while I thought that, but the hit to young people is at the center of the whole enterprise,' Impey says. 'It's like pulling the rug out from under the whole thing." It's not just brain drain of existing talent, he says. Students who are in high school and college now and thinking about a career in research might reconsider. "There's plenty of things smart kids can do. They don't have to go into science." At the same time, McNutt says she tells students: "If you went into graduate school in the fall of this year, by the time you get your PhD, this madness may be over. You come out with your new PhD ready to fill the gap."

Indian dealers offer steeper discounts as price rally dulls demand
By Rajendra Jadhav and Brijesh Patel (Reuters) - Gold discounts in India widened this week to their highest levels in more than a month, as a rally in domestic prices to near-record highs weighed on demand, while elevated rates also dampened buying across other major Asian hubs. Domestic gold prices were trading around 98,300 rupees per 10 grams on Friday, after rebounding from a low of 90,890 rupees last month and nearing the all-time high of 99,358 rupees. The spike in prices forced Indian dealers to offer discounts of up to $56 an ounce below official domestic prices, which include a 6% import duty and 3% sales tax, up from $31 last week. "Prices have gone up, and that's really hit demand. Hardly anyone was buying this week," said Harshad Ajmera of wholesaler JJ Gold House in Kolkata. Gold demand in India typically remains subdued during the monsoon season, which began earlier than usual this year. Jewellers are not making purchases because the lean demand season has started, and they don't want to build high-cost inventory, said a Mumbai-based bullion dealer with a private bank. Meanwhile, dealers in top gold consumer China charged premiums of $10-$14 an ounce over the global benchmark spot price. Last week, bullion changed hands at par to a $15 premium. "Elevated gold prices appear to have negatively impacted Chinese demand, judging by weaker trading volume," said Hugo Pascal, a precious metals trader at InProved. In Hong Kong, gold was sold at a premium of $0.30 to $1.30, while in Singapore gold traded between at-par prices and a $2.50 premium. "We've seen some of our clients coming to take profit and also on the wholesale side, we've seen some selling because prices are high," said Brian Lan, managing director at Singapore-based GoldSilver Central. In Japan, bullion traded anywhere between a discount of $0.5 and a $0.5 premium over spot prices.

MAGA's Grip on Republican Party Wobbles, Poll Suggests
Based on facts, either observed and verified firsthand by the reporter, or reported and verified from knowledgeable sources. Newsweek AI is in beta. Translations may contain inaccuracies—please refer to the original content. The share of Republicans who identify as "MAGA Republicans" appears to have plateaued—and may even be slipping—according to a new poll. An Economist/YouGov poll conducted from May 30 to June 2 among 1,610 adults found that 49 percent of Republicans now describe themselves as "MAGA Republicans," a drop from previous months and only a modest increase from 38 percent in September 2022. Among all U.S. adults, 16 percent now embrace the MAGA label, up slightly from 11 percent two years ago, but down from a peak of 20 percent in March. Why It Matters Since his first term, Trump has consolidated the Republican Party around not only himself but also his broader "Make America Great Again" movement. But the latest findings indicate that, while Trump still commands deep loyalty among a significant portion of the GOP base, his branding power may be reaching its ceiling—or even entering a phase of fatigue or redefinition. What To Know The share of Republicans who identify as "MAGA Republicans" fell from a March peak of 60 percent in March. Since then, Republican identification with MAGA has continued to fall, declining to 47 percent in April, before going back up to 55 percent at the end of May. But, in the past few weeks, the share of Republicans who identify as MAGA has declined again.

Seth Wenig/AP Among the broader U.S. adult population, the MAGA label has never attracted more than 20 percent support. YouGov/Economist polling shows that Republican men (59 percent) are still more likely than Republican women (45 percent) to identify as MAGA. Such self-identification is also higher among union members (60 percent), veterans (62 percent), very conservative voters (73 percent), and those who closely follow public affairs (63 percent). While most Republicans still approve of Trump, MAGA Republicans are far more enthusiastic. In the latest poll, 97 percent of MAGA Republicans approve of Trump's job performance—a number that has remained steady. But approval among non-MAGA Republicans has dropped 18 points since January, and disapproval has jumped 21 points, with a particularly sharp decline in strong approval. The split extends to personal opinions: just 23 percent of non-MAGA Republicans say they like Trump personally "a lot," compared to 68 percent of MAGA Republicans. The economy may be a key reason some Republicans are distancing themselves from the MAGA brand. After Trump's election, MAGA Republicans became far more optimistic, with 58 percent now saying the economy is improving and 64 percent expecting their household finances to improve. However, among non-MAGA Republicans, only 31 percent say the economy is getting better, and just 36 percent expect better finances ahead. The polling is in line with the general trend in recent months, which has shown sagging numbers for the president following the introduction of his "Liberation Day" tariffs in April. The policy move rattled markets, prompting a sharp sell-off before an eventual recovery. But public sentiment did not rebound as quickly as the Dow. Polls throughout April and much of May showed a decline in his national approval ratings and his ratings on the economy. However, polls now suggest that the bleeding has stopped, as economic anxiety has somewhat subsided. In the latest ActiVote poll, Trump's approval rose to 46 percent, up from 45 percent last month, while disapproval dropped to 50 percent. This marks a break from months of decline and puts Trump above his average first-term approval rating of 41 percent, and also above former President Joe Biden's average approval. Similar gains were observed in polls by YouGov/Economist (45 percent approval, up one point), TIPP Insights (43 percent, up one), Civiqs, Trafalgar Group (54 percent approval, up sharply), and Quantus Insights (49 percent, up one). A John Zogby Strategies poll showed Trump holding a strong 58 percent approval, with disapproval down a point. And, in the latest RMG Research poll. Trump's approval was up 5 points to 51 percent. Newsweek's poll tracker also shows Trump's approval rating trending upward, currently showing that an average of 47 percent approve of his job performance, while 49 percent disapprove. A month ago, in the tracker, the president's approval rating stood at 44 percent, while his disapproval rate was firmly in the 50s. But, like the MAGA poll, not all polls show an upswing. A YouGov/Yahoo poll showed Trump dipping to 41 percent, and Morning Consult recorded a drop from 48 percent to 46 percent in recent weeks. What Happens Next As the effects of his economic, immigration and other major policies come into sharper relief, Trump's approval rating is likely to fluctuate.
