    NATO’s London meetings are off to a rocky start

    By: Sebastian Sprenger LONDON — U.S. President Donald Trump landed Tuesday in London with a splash, decrying French President Emmanuel Macron's recent description of NATO as brain dead, calling it a “nasty” assessment and unfair to the alliance. Trump's remarks on the eve of a meeting of government leaders here on Wednesday come as NATO members are already on edge about myriad internal differences. Clashing views have become so pronounced in the last few weeks that some observers fear the worst for what has been billed as NATO's 70th birthday bash. “You just can't go around making statements like that about NATO,” Trump said of Macron in a joint news conference with Secretary General Jens Stoltenberg. “It's very disrespectful.” The U.S. president's words are remarkable not for their tone — he also delivered an en passant bashing of French politics and economy — but for the substance of the argument. Trump, who has shown a deep disdain for the mere principle of multilaterlism, appears to be shielding NATO from Macron's critique, which in turn was partly aimed at himself. Talk about the three-dimensional chess of geopolitics. Or something like that. Stoltenberg, for his part, sought to downplay any cracks within the alliance, arguing in typical fashion that healthy squabbling should be expected in any group of countries working together. “If you look at the substance, you can see that the alliance is delivering,” he said at the NATO Engages think tank event in central London. He named ongoing operations to secure the eastern flank against Russia, the training of security forces in Iraq and an uptick in defense spending by all allies in recent years as examples of an alliance that continues to be operationally relevant. Stoltenberg was noncommittal, however, on the latest curveball thrown by member country Turkey. The Turks want their perception of a terrorist threat posed by YPG Kurdish units to their border with Syria recognized by all of NATO as a quid pro quo for backing the alliance's bolstering of the Baltics. Such a deal could cause a significant rift. Trump is an admirer of Turkish President Recep Tayyip Erdoğan, and will likely get more deeply involved in the issue during meetings here. “Turkey does not question the alliance, but rather Turkey expects an understanding of the threat of terrorism to one of its allies,” Gülnur Aybet, Erdogan's senior adviser on foreign policy, told the NATO Engages audience. “We don't question the credibility of Article 5. On the contrary, we expect it to be fulfilled,” she added, referring to the alliance's creed that an attack on one member will prompt a response by all. https://www.defensenews.com/smr/nato-2020-defined/2019/12/03/natos-london-meetings-are-off-to-a-rocky-start/

    DARPA official: To build trust in AI, machines must explain themselves

    By: Brandon Knapp Artificially intelligent systems must be able to explain themselves to operators if they are to be trusted, according to an expert from the Defense Advanced Research Agency, who voiced concern that methods used by current AI systems are often masked by mysterious algorithms. “A lot of the machine learning algorithms we're using today, I would tell you ‘good luck,” Fred Kennedy, the director of DARPA's Tactical Technology Office during a panel at Navy League's Sea-Air-Space on April 10. “We have no idea why they know the difference between a cat and a baboon.” “If you start diving down into the neural net that's controlling it,” Kennedy continued, “you quickly discover that the features these algorithms are picking out have very little to do with how humans identify things.” Kennedy's comments were in response to Deputy Assistant Secretary of the Navy for Unmanned Systems Frank Kelley, who described the leap of faith operators must make when dealing with artificially intelligent systems. “You're throwing a master switch on and just praying to God that [Naval Research Laboratory] and John's Hopkins knew what the hell that they were doing,” Kelley said of the process. The key to building trust, according to Kennedy, lies with the machines. “The system has to tell us what it's thinking,” Dr. Kennedy said. “That's where the trust gets built. That's how we start to use and understand them.” DARPA's Explainable Artificial Intelligence program seeks to teach AI how to do just that. The program envisions systems that will have the ability to explain the rationale behind their decisions, characterize their strengths and weaknesses, and describe how they will behave in the future. Such capabilities are designed to improve teamwork between man and machine by encouraging warfighters to trust artificially intelligent systems. “It's always going to be about human-unmanned teaming,” said Kennedy. “There is no doubt about that.” https://www.defensenews.com/home/2018/04/10/darpa-official-to-build-trust-in-ai-machines-must-explain-themselves/

    The Countries Where F-35 Sales Are Taking Off

    Since the first F-35 rolled off Lockheed Martin's production line in 2006, the fifth-generation multirole stealth fighter has taken the world by storm. U.S. F-35s deployed to Europe and the Pacific in 2017, and Israel has reportedly already used its jets in combat in the Middle East. Soon, the Arab world might get its first F-35 — the United Arab Emirates is in talks with the United States about buying the aircraft. To date, the program's reach has expanded to 12 nations around the globe, and all signs point to the F-35 continuing to dominate the Western fighter market for decades to come. But tensions between historically close NATO allies could threaten the fate of one partner nation's F-35 fleet: Turkey. Here's the breakdown of the global F-35 fleet. https://foreignpolicy.com/2018/06/22/the-countries-where-f-35-sales-are-taking-off/
