目前,战略核武器处于既削减又发展的阶段。冷战结束后,美、俄、英、法等核国家相继调整了核政策,不同程度地削减了核力量,暂停了核试验。但几个核国家都继续主张保持一支有效的核威慑力量,以遏制新形势下的战争。此外,日本和印度已具备研制核武器的能力,并储备了大量核材料,可以说,它们已跨在了核“门槛”上。 At present, strategic nuclear weapons are in a phase of reduction and development. After the Cold War ended, nuclear states such as the United States, Russia, Britain, France and China successively adjusted their nuclear policies, reduced their nuclear forces to varying degrees, and suspended nuclear tests. However, several nuclear states continue to advocate the maintenance of an effective nuclear deterrent to contain the war in the new situation. In addition, Japan and India already have the capability to develop nuclear weapons and reserve a large amount of nuclear materials, so to speak, they have already crossed the “threshold” of nuclear weapons.
