俄美唯一核军控条约失效，特朗普最新表态

Core Viewpoint - The expiration of the U.S.-Russia New Strategic Arms Reduction Treaty (New START) on February 5 raises concerns about the potential for increased nuclear arms competition and instability in global security, as it marks the first time in over half a century that there are no binding limits on the strategic nuclear arsenals of the two countries [7][9][10]. Group 1: Treaty Background and Expiration - The New START treaty was signed in 2010 to limit the number of deployed nuclear warheads and delivery systems, originally set to last for 10 years and extended to February 5, 2026 [3][10]. - The treaty allowed for up to 18 on-site inspections per year, fostering communication and predictability between the U.S. and Russia [34]. - The expiration of the treaty signifies a loss of the last legal constraints on the expansion of nuclear arsenals for both nations [33][34]. Group 2: Reactions and Future Implications - President Trump criticized the treaty as a "bad deal" and suggested that a new, modernized agreement should be pursued instead of extending the existing one [20][22]. - Russian officials, including Deputy Chairman of the Federation Council Kosachev, stated that the treaty's termination would not lead to a new arms race or nuclear war, asserting that the world would not collapse [6][25]. - The international community has expressed concerns that the lack of a treaty could lead to increased nuclear competition and a more dangerous global environment, with calls for both nations to return to negotiations [9][14][35]. Group 3: Strategic Stability and Global Security - The expiration of the treaty is viewed as a significant step back in maintaining strategic stability, with the risk of nuclear weapon use at its highest level in decades [10][29]. - Analysts warn that the absence of structured diplomatic dialogue may increase the likelihood of misunderstandings and miscalculations between nuclear powers [33][35]. - The potential for other nuclear-capable nations to reconsider their non-proliferation commitments due to the uncertainty surrounding U.S. security guarantees has also been highlighted [33].
