The non-Soviet members of the Warsaw Pact contributed to the end of the Cold War along with the superpowers. These Eastern European states recognized that their relationship with the Soviet Union would impede their success in the post–Cold War world, so they ended the Pact.

Matthew Evangelista examines the precedents and possibilities for postwar European security in an interview with International Security Executive Editor Jacqueline L. Hazelton.

States frequently acquire proof that other states have violated norms. Yet, existing theories do not fully explain how states wield such proof to coerce wrongdoers. Four case studies of nuclear proliferation probe a novel theory of how states coerce norm violators by concealing, sharing privately, or publicizing proof of guilt.

Two variables help determine whether ideological enemies are likely to ally against a shared material threat. States’ susceptibility to domestic ideological changes and the nature of states’ ideological differences are two contending forces that influence alliance formation or failure.

Elias Götz responds to Michael McFaul’s fall 2020 article, “Putin, Putinism, and the Domestic Determinants of Russian Foreign Policy.”

Did the Western powers promise in 1990 not to expand NATO? An examination of the evidence leads to the conclusion that the Russian allegations are by no means baseless, which affects how the U.S.-Russian relationship today is to be understood.

Why did Russia’s relations with the West shift from cooperation a few decades ago to a new era of confrontation today? Tracing the causal influence of domestic determinants—individuals (President Vladimir Putin), ideas (Putinism), and institutions (autocracy)—reveals Putin’s significant influence in the making of Russian foreign policy.

China has the world’s largest army. Russia wields the most tanks. America owns the fanciest satellites. But who has the most cyber-power? A new National Cyber Power Index by the Belfer Centre at Harvard University ranks 30 countries on their level of ambition and capability. Offensive cyber-power—the ability to do harm in or through computer networks—is one measure. But so too are the strength of a country’s defences, the sophistication of its cyber-security industry and its ability to spread and counter propaganda.

As conventional wisdom goes, experts tend to rank the U.S ahead of China, U.K., Iran, North Korea, Russia, in terms of how strong it is when it comes to cyberspace. But a new study from Harvard University’s Belfer Center shows that China has closed the gap on the U.S. in three key categories: surveillance, cyber defense, and its efforts to build up its commercial cyber sector.

“A lot of people, Americans in particular, will think that the U.S., the U.K., France, Israel are more advanced than China when it comes to cyber power,” Eric Rosenbach, the Co-Director of Harvard’s Belfer Center, told CyberScoop. “Our study shows it’s just not the case and that China is very sophisticated and almost at a peer level with the U.S.”

The administration of President Donald J. Trump has consistently used fear of China to undermine nearly five decades of bipartisan consensus on US–Russian nuclear arms control. The negative consequences of these actions may last far beyond the Trump presidency. If generations of agreement between Democrats and Republicans on bilateral nuclear treaties with Russia erode, it will pose a significant setback to US national security and global stability. Future leaders may ultimately need to consider new approaches to nuclear risk reduction that preserve the benefits of the arms control regime.
