    Why the U.S. could lose the next big war - and what that means for Canada

    Murray Brewster · CBC News It was more than the usual sky-is-falling rhetoric we're used to seeing in national security reports out of Washington. It came from some pretty sober, respected voices in the defence community. A special commission report, presented to the U.S. Congress this week, delivered one of the most stark — even startling — assessments in the last two decades of the limits of American military power. The independent, nonpartisan review of the Trump administration's 2018 National Defence Strategy said the U.S. could lose future wars with Russia or China. "This Commission believes that America has reached the point of a full-blown national security crisis," reads the 116-page document written by 12 leading defence and security experts and released Wednesday. "If the United States had to fight Russia in a Baltic contingency, or China in a war over Taiwan, Americans could face a decisive military defeat." Those are sobering words for Canada, in light of this country's contribution of over 450 troops to the NATO-led deterrence mission in Latvia. Time for a defence policy rewrite? And it has prompted a call from at least one Canadian defence expert for a re-assessment — perhaps even a full-blown rewrite — of the Liberal government's own defence policy. More than simply another rote, boilerplate plea for fatter U.S. defence budgets, the commission's report lays out in precise detail the kind of geopolitical threats Washington — and, by extension, other Western capitals — are facing from rivals and enemies at many levels and in multiple spheres. "The security and well-being of the United States are at greater risk than at any time in decades. America's military superiority — the hard-power backbone of its global influence and national security — has eroded to a dangerous degree," says the report. "America's ability to defend its allies, its partners, and its own vital interests is increasingly in doubt. If the nation does not act promptly to remedy these circumstances, the consequences will be grave and lasting." The report acknowledges that the U.S. and its allies may be forced to fight a localized nuclear war in the future, given how Russia has restored the once-unthinkable concept to its military planning and training exercises. The commission also paints various grim scenarios that could confront Western allies between now and 2022, including an invasion of the Baltics under the guise of a "peacekeeping" mission to protect Russian minorities: "As U.S. and NATO forces prepare to respond, Russia declares that strikes against Russian forces in those states will be treated as attacks on Russia itself — implying a potential nuclear response. "Meanwhile, to keep America off balance, Russia escalates in disruptive ways. Russian submarines attack transatlantic fibre optic cables. Russian hackers shut down power grids and compromise the security of U.S. banks." The consequences, said the report, would be severe: "Major cities are paralyzed; use of the internet and smartphones is disrupted. Financial markets plummet as commerce seizes up and online financial transactions slow to a crawl. The banking system is thrown into chaos." While the report doesn't mention U.S. President Donald Trump by name, it notes the effect of his bruising rhetorical fights with world leaders and criticism of international institutions, such as NATO. "Doubts about America's ability to deter and, if necessary, defeat opponents and honour its global commitments have proliferated," said the report. Cautious optimism At this weekend's Halifax International Security Forum, Canada's marquee defence conference, some leading experts struck a less pessimistic note and suggested that the West still has a major technological lead on Moscow. "Russia is a great country. It is a great country, historically. But Russia is also a failing country," said Peter Van Praagh, president of the Halifax Security Forum, at the opening of the event on Friday. "Russia does not have the same advanced tools that NATO has, that Canada and NATO and the American alliance [have]." Defence Minister Harjit Sajjan also expressed cautious optimism about the threat. "In NATO we're taking this extremely seriously. We're learning from the various missions that are ongoing," he said. A former military adviser to one of Sajjan's predecessors said Canada could learn from the commission exercise, which was meant to challenge the Trump administration's defence plans. "It's certainly something we don't have," said Richard Cohen, an ex-army officer who served as former defence minister Peter MacKay's adviser. "Our government would never dream of inviting anyone to come and criticize its defence policy." The current government sought extensive input before the new Canadian policy was presented 18 months ago. The U.S. commission report calls on NATO and its allies to "rebuild" substantial military forces in Europe, among things. Cohen said that, if anything, should trigger a fresh look at the Liberal government's own defence policy. "Our defence policy is predicated on the kind of asymmetric warfare we have faced since the end of the Cold War and it really ignores the looming strategic threats that Russia, China and maybe some others pose as well," he said. "At least the United States realizes this growing strategic threat," Cohen added, noting that the current Liberal defence policy makes only passing mention of China "in very gentle terms" and limited references to Russia. "If the United States is in a national security crisis, then we're in a national security crisis." https://www.cbc.ca/news/politics/defence-policy-trump-china-russia-1.4910038

    Japan commits to local F-35 production

    by Jon Grevatt The Japanese Ministry of Defense (MoD) has confirmed plans to continue the local production of Lockheed Martin F-35 Lightning II Joint Strike Fighter aircraft. The move reverses a decision in late 2018 to cease local production at Japan's final assembly and checkout (FACO) facility in Nagoya and instead focus on the localised maintenance, repair, overhaul and upgrade (MRO&U) of F-35s. That move was previously prompted by the high cost of building the F-35s at the facility. However, a spokesperson from the MoD told Janes that the new decision to continue building the aircraft at the Japanese FACO facility was influenced by the declining costs of producing the F-35 locally. Producing the aircraft locally, said the spokesperson, is now cheaper than importing the F-35 from the United States. The spokesperson was speaking to Janes nearly three weeks after the United States government approved a potential USD23 billion deal to sell Japan an additional 105 F-35s. This Foreign Military Sale means Japan will operate a total of 147 F-35s, becoming the second-largest operator of the aircraft in the world. These aircraft will comprise 105 conventional take-off and landing (CTOL) F-35A aircraft and 42 units of the short take-off and vertical landing (STOVL) F-35B. The spokesperson said, “For the acquisition of F-35As in fiscal years (FY) 2019 and 2020... the Japanese MoD has decided to use domestic manufacturing at the FACO... It is confirmed that the unit cost of aircraft produced at the domestic FACO [facility] is less, compared to the unit cost of imported aircraft.” https://www.janes.com/defence-news/news-detail/japan-commits-to-local-f-35-production
