The American government has not set a good example, having already abandoned the Anti-Ballistic Missile treaty, binding limitations on testing nuclear weapons and developing new ones, and a long-standing policy of foregoing threats of “first use” of nuclear weapons against non-nuclear states. These recent decisions have encouraged China, Russia, and other NPT signatories to respond with similar actions.
美国政府由于摒弃限制核武器实验和发展新型核武器的《反弹道导弹公约》和长期坚持威胁对无核国家“首先使用”核武器的政策，因而没有起到表率作用。最近的这些决策更是引得中国、俄罗斯等其他NPT的缔约国也纷纷效仿。
