In a series of unusually candid remarks, the US general in charge of the nation's nuclear arsenal has issued a stark warning that Russia and China are "aggressively" developing new high-speed, or hypersonic, weapons that the US currently has no defense against.The weapons might not be operational for several years, but Gen. John Hyten, the four-star head of US Strategic Command, is warning that changes to missile defenses are urgently needed or the US will be unable to detect them when they are operational."China has tested hypersonic capabilities. Russia has tested. We have as well. Hypersonic capabilities are a significant challenge," Hyten told CNN in an exclusive interview. "We are going to need a different set of sensors in order to see the hypersonic threats. Our adversaries know that."Hyten and other military officials say the current generation of missile detecting satellites and radars won't be enough to detect these new generation weapons. Hypersonic is generally defined as a speed of Mach 5 or over 3,806 miles per hour."We've watched them test those capabilities," Hyten told Congress last week. But with unusual public candor about potential US military shortfalls, he acknowledged "we don't have any defense that could deny the employment of such a weapon against us, so our response would be our deterrent force, which would be the triad and the nuclear capabilities that we have to respond to such a threat."Hypersonic missiles fly into space after launch, but then come down and fly at high speeds on a flight path similar to an airplane. Their lower trajectory make them more difficult for US missile defense satellites and radars to detect. Russia has openly stated it is developing high-speed air-launched missiles as well as underwater hypersonic drones.The Pentagon is currently writing a review of its missile defenses to help determine what new capabilities might be needed to deal with new classes of attack weapons. Hyten gave Congress a hint of what may be in that review stating "the first thing we need is better sensor capability, better tracking capabilities to make sure we can characterize and then respond to that threat."He also called for improved US warheads, essentially "better kill vehicles on the top of our interceptors so that those kill vehicles become more and more lethal." The Pentagon is also working on concepts for interceptor missiles that repel a barrage of enemy attack missiles. Current US missile defenses are designed to only shoot down a small number of enemy missiles.The US focus has largely been to work on hypersonic technologies across the board. But Russia is now well into testing some of its systems. Earlier this month Russia showed video of what the Kremlin said was an air-launched hypersonic ballistic missile.When asked how far along the Russian hypersonic program is, Hyten told CNN, "I don't want to put a who's winning the race, I'll just say there is a race."When asked how soon it could be before the Russians have an operational hypersonic weapon that could reach the US, Hyten said, "It's similar to the North Korea problem. If you continue to pursue that technology, you will get there. And the Russians will get there, the Chinese will get there and we'll get there -- and we'll have to figure out how to deal with that." 3323

In a phone interview with Fox News on Monday, President Donald Trump remembered his brother Robert as a "fantastic guy" and his "best friend."Robert Trump died over the weekend at the age of 71. The president was able to visit his brother in New York before his passing."This was not a great weekend; it's very hard," Trump said. "You knew it was going to happen, but still — when it happens, it's a very tough thing.""He was a great guy, he was a tremendous guy. He was my friend, I guess they say 'best friend,' and that's true," Trump added. "And losing him...not easy."Trump said that throughout his life his relationship with his brother was free of jealousy despite growing up in a competitive environment."A lot of times in families, I hate to say it, but there's jealousy, especially among children and children who are competitive children, because he was very competitive," Trump told Fox News on Monday. "There was not an ounce of jealousy. He'd go around talking about how great this is for the country and it's so incredible. He was my biggest fan."Trump added that his brother was "thrilled" at his work as president."People would tell me all the time, 'I spoke to your brother, and your brother was so thrilled and so thrilled at what was happening and what was happening for the country,'" Trump said. "He was so angry at China because of what happened when the plague came in and they shouldn't have allowed that to happen. They could have stopped it. He was so upset by that."Later, in a gaggle with reporters prior to departing for Wisconsin, Trump said that he may hold a funeral service for his brother at the White House on Friday. 1661

If you can't beat Amazon, partner with it.Kohl's is doing another deal with Jeff Bezos. The department store chain said Tuesday that 82 stores in the Chicago and Los Angeles areas will soon accept return items from Amazon. Kohl's will pack and ship the merchandise back to the online retailing giant for free.Earlier this month, Kohl's announced a plan to sell the Alexa-enabled Echo home speaker, Fire TV, tablets and other Amazon-branded devices in 10 of its stores.The latest partnership between Kohl's and Amazon comes as traditional retailers try (and often fail) to adapt to a rapidly changing landscape. Toys 'R' Us filed for bankruptcy protection late Monday.Toys 'R' Us has been hurt by Amazon, as well as Walmart and Target. But other retailers are following the lead of Kohl's and have decided to work more closely with Amazon to boost sales.Sears, which also owns Kmart, has been one of the worst-performing retailers of the past decade. But the company announced in July that it would sell Kenmore appliances, including some that are compatible with Alexa, on Amazon.Related: Wall Street bets Amazon will doom department storesCooper Smith, director of Amazon research at L2, a firm that tracks the digital performance of brands, says he expects more retailers to partner with Amazon -- but they will need to be wary at the same time."Doing deals with Amazon makes sense. They can help get consumers to come back, especially around Black Friday," he said. "But these retailers will have to tread a careful line when partnering with Amazon."That's because Amazon isn't just working with other retailers. The company has opened its own physical stores, Amazon Books, that sells best-selling books and Amazon devices.And in its biggest brick-and-mortar move of all, Amazon bought Whole Foods this year for nearly billion. The deal recently closed, and now you can buy Amazon gadgets at the grocery store along with kale and quinoa.It should come as no surprise, then, that investors in Barnes & Noble and Kroger aren't too pleased with Amazon's increased clout in the real world. The stocks of both companies have plunged nearly 40% this year, while Amazon is up 30%.L2's Smith notes that Amazon has its sights set on clothing, too. That could pose a problem for Kohl's and Sears."Amazon is launching private label apparel brands of its own," Smith said, adding that this could hurt sales of bargain-priced fashion at Kohl's, Sears and other department stores.Related: Nordstrom may reinvent itselfNot every big traditional retailer is throwing in the towel.Chuck Grom, an analyst with Gordon Haskett, notes that Macy's recently hired Hal Lawton, formerly a senior executive at eBay, to be its president. Nordstrom is launching a format called Nordstrom Local with no inventory. The Local stores will have stylists who help people pick out clothes that they can order online. The stores will serve wine and beer, too."We continue to observe more and more collaboration between digitally native companies and traditional retailers -- a theme that we think will continue to build momentum in the coming quarters," Grom wrote in a report Tuesday.And Walmart continues to boost its own digital operations under the leadership of Marc Lore, who joined the retailer after Walmart bought his company Jet.com last year."Walmart has done an extremely great job online under Lore," Smith said. "It's shaping up to be an all-out price war between Walmart and Amazon, and if anyone can beat Amazon at its own game, it's Walmart."The-CNN-Wire? & ? 2017 Cable News Network, Inc., a Time Warner Company.

House Minority Leader Nancy Pelosi says the Republican tax plan isn't all that it seems, expressing her frustration over a lack of collaboration between the two parties.Speaking with CNN's Jake Tapper on "State of the Union" Sunday morning, Pelosi said President Donald Trump and Republicans are moving too fast."If you're going to do a whole revision of the tax code, it should be done in a bipartisan way. That's the only way it will be fair, simplified, and sustainable. ... They're trying to move this in a matter of days," she said.Despite claims of tax cuts to middle class families, there are other factors in the tax plan to consider, Pelosi said. 663

In a move surely intended to put Washington on notice China's military has put on a show of force in the South China Sea, new satellite images show, with drills at sea and in the air to reinforce its claims in the contested region.Analysts said the images, provided by Planet Labs Inc and date-stamped March 26, showed China's only operational aircraft carrier, the Liaoning, accompanied by dozens of other vessels in the South China Sea, just south of the Chinese island province of Hainan.While the aircraft carrier has visited the South China Sea before, it was unusual to see such a large number of Chinese naval vessels training together in the area, Collin Koh, research fellow at the S. Rajaratnam School of International Studies' Maritime Security Program, told CNN."I would say this is the new normal and this will not be a one-off show of force," he said. 873
