Joseph Nye argues that the "one China" formula, if combined with other measures to bolster deterrence against any sudden acts of aggression, can still help to keep the peace.

Prior to October 7, 2023, the defining feature of Israeli foreign policy was the drive to normalize ties with Arab states, thereby "shrinking” the Israeli–Palestinian conflict and assembling Iran's rivals into a broad regional coalition. Despite the endurance of interests that made such a pursuit desirable, the most lucrative selling point of normalization—the ability to develop it into a diplomatic construct with which to contain Iran—had already expired prior to October 7, along with the essential contextual condition for such a deal: broad US support. Rather, the "Age of Normalizations," a period in which diplomatic normalization could feasibly serve as the kernel of Israeli strategy, expired in late 2021 as a consequence of the Biden administration's volte-face in the Middle East.

This week in Say More, Project Syndicate talks with Joseph S. Nye, Jr., an emeritus professor at Harvard Kennedy School, a former U.S. assistant secretary of defense, and the author, most recently, of A Life in the American Century.

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.

Stephen Walt writes that those who favor foreign policy restraint believe the United States should trade and invest in other countries, encourage other states to do the same, and be open to managed immigration instead of building walls in a fit of xenophobia.

After a century of rebellion, South America experienced a rapid decline in revolts in the early 1900s. Historical narratives and an analysis of a comprehensive new dataset show that the decrease stemmed in large part from the expansion and professionalization of the region’s militaries, which were driven by an export boom and the threat of interstate conflict. 

Russia's 2022 invasion of Ukraine illuminated the long profound shadow of nuclear weapons over international security. Russia's nuclear threats have rightfully garnered significant attention because of the unfathomable lethality of nuclear weapons. However, the use of such weapons in Ukraine is only one way—albeit the gravest— that Russia could challenge the global nuclear order. Russia's influence extends deep into the very fabric of this order—a system to which it is inextricably bound by Moscow's position in cornerstone institutions such as the Nuclear Non-Proliferation Treaty (NPT) and the International Atomic Energy Agency (IAEA). From withdrawing from key treaties to stymieing resolutions critical of misconduct, Moscow has demonstrated its ability to challenge the legitimacy, relevance, and interpretations of numerous standards and principles espoused by the West.

Stephen Walt argues that bringing Ukraine into NATO now is a bad idea that will prolong the war and leave Kyiv in an even worse position over time.

Joseph Nye considers lessons from his own work on preventing the spread of nuclear technology in the 1970s.
