Stephen Walt writes that the future will be determined by a handful of big questions: What is China's future trajectory; How good are America's cybercapabilities; What's going to happen to the EU; How many states will go nuclear in the next 20 years; and Who will win the debate on U.S. grand strategy?

The U.S. government is currently working on creating a so called Space Force. Legislation to establish the branch is expected to be included in the Pentagon's budget proposal next year, but it would still need approval from Congress.

If the Space Force branch is established, tech companies and defense contractors in Massachusetts stand to make millions — if not billions — in new contracts.

You may not realize it, but you probably interact with some space object every day. Maybe it’s your car, your television or even your internet — each relies on some space-orbiting satellite to function. Satellites are accessed by millions of devices a day and are robust providers of service. But trusting these satellites as much as we do is risky as they are all extremely vulnerable to cyberattacks.

When we think about critical infrastructure, the first assets that come to mind include the electric grid, water networks and transportation systems. Further unpacking the definition of critical infrastructure, we consider industries such as agriculture, defense or the financial sector. However, we rarely think about where the underlying systems that enable technology functionality across these sectors physically reside, who developed the technology, and who can access and manage that technology.

Building effective cyber defenses is a major challenge for defense planners, just as missile defense has been since the original Strategic Defense Initiative. In both realms the offense has the advantage, making effective defense difficult. Missile defense, however, now has several decades of experience producing and fielding new technologies. The Project on Military and Diplomatic History hosted a panel discussion of CSIS experts and Michael Sulmeyer of the Belfer Center on the history of missile defense, its experience in developing new technologies, and what these tell us about the prospects for building effective cyber defenses.

Former Deputy Secretary of Energy Elizabeth Sherwood-Randall is joining Harvard Kennedy School’s Belfer Center for Science and International Affairs as a Senior Fellow, the Center announced today. Sherwood-Randall, who has served in the White House and Departments of Energy and Defense, is returning to the Center where she worked in the 1990s to help establish two pioneering projects – the Strengthening Democratic Institutions Project with Graham Allison, who this month stepped down as the Center’s director, and the Preventive Defense Project with Ash Carter, the former Secretary of Defense who is the new Belfer Center director.

Putin and his government seek respect, stability from next U.S. administration, panel says.

In this report, American Nuclear Diplomacy: Forging a New Consensus to Fight Climate Change and Weapons Proliferation, Former Deputy Secretary of Energy and Belfer Center Senior Fellow Daniel Poneman writes that we face two existential threats: nuclear annihilation and catastrophic climate change. Each, he says, stems from human origins. Both must be fought aggressively.

"Multiple studies confirm the grim truth that, even if all nations fulfill their Paris Climate Agreement emissions pledges, the world will still far overshoot the 2°C warming limit scientists say we must not exceed to prevent devastating climate impacts. Carbon-free nuclear energy can help close the gap. But can we expand its environmental benefits without increasing the risks of nuclear terror?"

Poneman outlines a diplomatic strategy and tough-minded, bipartisan policies to get us there.
