Neither Russia nor China has ever deployed nuclear weapons against civilian populations, a distinction held solely by the United States. Their reasons for restraint diverge significantly, rooted in distinct strategic and cultural priorities, yet China’s rising global influence positions it as a greater long-term threat to the United States than Russia, despite Russia’s more overt aggression.

Russia’s behavior, exemplified by the 2014 annexation of Crimea and the 2022 invasion of Ukraine, reflects an aggressive posture driven by a desire to counter NATO’s eastward expansion and maintain regional dominance. However, its economic challenges sanctions, energy export dependence, and a GDP of approximately $2.1 trillion in 2023 (World Bank) constrain its global reach, rendering it a struggling, though resilient, power. With the world’s largest nuclear arsenal, Russia’s restraint in nuclear use stems from a pragmatic focus on national survival. Its actions prioritize geopolitical relevance over a quixotic pursuit of Soviet-era glory, but its declining economic and demographic strength limits its capacity to challenge the United States on a global scale.

In contrast, China’s non-use of nuclear weapons aligns with its cultural and strategic emphasis on economic expansion over territorial conquest. Through initiatives like the Belt and Road Initiative, which has invested over $1.2 trillion globally since 2013, China has built a network of economic influence. Its military modernization, backed by a $292 billion defense budget in 2023 (SIPRI) and a nuclear arsenal projected to reach 1,000 warheads by 2030, complements this economic dominance. While China’s “no first use” nuclear policy, established in 1964, reflects a commitment to strategic stability, its assertive actions such as militarizing the South China Sea and pressuring Taiwan signal a willingness to use force to secure economic and territorial interests. Unlike Russia’s regionally focused aggression, China’s global economic leverage, technological advancements, and growing military capabilities pose a more systemic challenge to U.S. primacy, particularly in critical domains like trade, technology, and Indo-Pacific influence.
