At the 2021 Shanghai Cooperation Organization (SCO) summit in Dushanbe, Tajikistan, the bloc announced the approval of Iran's longstanding bid for membership. The Islamic Republic has viewed its involvement in the organization as a means of bolstering external legitimacy, fostering security-oriented regionalism, and promoting the transition toward the so-called multipolar world order. The SCO, led by Russia and China, has served as a regime-preservation network by providing Iran with a source of solidarity against external pressure. Tehran's commitment to the normative order, sustained by the SCO's discourse of noninterference, sovereignty, and countering the “three evils”—terrorism, extremism, and separatism—has galvanized the organization's role as a common front against the imposition of liberal norms and challenges to regime security.

Atonement is an apology and reparations payments from one state to another for mass atrocities and other human rights abuses. The only case of atonement so far is that of West Germany and Israel in 1952. The West German decision to atone for the Holocaust was neither a moral choice nor the result of U.S. pressure. Instead, both countries saw atonement as politically expedient.

Scott Sagan asked Joseph S. Nye to revisit Nuclear Ethics, a book he published in 1986, in light of current developments in world affairs. In doing so, he found that much had changed but the basic usability paradox of nuclear deterrence remains the same. 

According to the "Madman Theory" outlined by Daniel Ellsberg and Thomas C. Schelling, and embraced by Presidents Richard Nixon and Donald Trump, being perceived as mad can help make seemingly incredible threats—such as starting a nuclear war—more credible.
