Nuclear Issues

"...[T]he United States has spent several tens of billions of dollars on missile defense research-and yet China, Iran, North Korea and possibly others have continued to pursue increasingly effective long-range ballistic capabilities. If missile defenses are a deterrent, why do US competitors-to say nothing of outright enemies-seem undeterred?"

"Keeping nuclear weapons and the difficult-to-manufacture materials needed to make them out of terrorist hands is critical to U.S. and world security — and to the future of nuclear energy as well. In the aftermath of a terrorist nuclear attack, there would be no chance of convincing governments, utilities, and publics to build nuclear reactors on the scale required for nuclear energy to make any significant contribution to coping with climate change."

"...[T]here are plenty of laws that require or authorize sanctions against governments that knowingly provide direct support to proliferators. But these laws offer little protection against those governments that—through neglect, corruption, or incompetence—fail to keep the materials and technology needed to make nuclear, biological, and chemical weapons from slipping out of their control and across their borders."

"...China is worried about how U.S. space weaponization plans might affect Chinese national security, international security, and protection of the space environment...."

"Chinese officials have expressed a growing concern that U.S. space and missile defense plans will stimulate a costly and destabilizing arms race...."

"China is concerned about U.S. missile defense and "space control"plans, which would lead to weaponization of outer space and stimulate a costly and destabilizing arms race. China is further concerned that the US missile defense program, as currently advertised, would neutralize China's strategic nuclear deterrent...."

A universal Fissile Material Cut-off Treaty (FMCT), which would ban the production of fissile material (separated plutonium, highly enriched uranium (HEU), and uranium-233) for nuclear weapons, has long been seen as a key building block in nuclear disarmament and non-proliferation.
