Calder Walton says both seek to topple the United States from atop world stage, with China's blend of money, influence, all-hands-on-deck approach posing the greater threat.

Stephen Walt analyzes the priority that the United States should place on competing with China by asking and answering five questions.

Joseph Nye argues that prudence results from the fear of creating unintended consequences in unpredictable systems and can develop into a norm of nonuse or limited use of certain weapons or a norm of limiting targets. Something like this happened with nuclear weapons when the superpowers came close to the brink of nuclear war in 1962, during the Cuban missile crisis. The Limited Test Ban Treaty followed a year later.

In the wake of a series of damaging cyber intrusions on private businesses controlling critical pieces of U.S. infrastructure, Harvard Kennedy School Senior Lecturer Juliette Kayyem says that countering the growing threat will require erasing the "legal fiction" that cyberattacks are different than physical attacks on American civilians.

Even if formal cybersecurity treaties are unworkable, it may still be possible to set limits on certain types of civilian targets, and to negotiate rough rules of the road. Whether U.S. President Joe Biden succeeded in launching such a process at his meeting last month with Russian President Vladimir Putin may become clear soon.

Bruce Schneier and Tarah Wheeler describe the future of war as cyberwar. They advise that if weapons and systems aren't secure, don't even bother bringing them onto the battlefield.

Tarah Wheeler critiques a new book, This Is How They Tell Me The World Ends by Nicola Perlroth, and concludes that it gets the policy recommendations right while making technical errors that could undermine trust in its conclusions.

When the Internet began to flourish in the 1990’s, there was an assumption that it would foster the values that the United States and its European allies held dearest: Freedom of expression, the spread of democracy, the empowerment of the individual. Presidents, prime ministers and German chancellors embraced the idea that the world’s democracies would be bound together, and that over time greater connectivity would enhance not only trade and understanding, but the alliance. 

Now, a new reality is dawning.

Bruce Schneier recommends that the United States improve government software procurement. Scrutiny cannot end with purchase: Security requirements need to be monitored throughout the software's life cycle, along with what software is being used in government networks.

Drawing on two decades of government efforts to “secure the homeland,” experts offer crucial strategic lessons and detailed recommendations for homeland security.
