| Summary/Abstract |
Twenty years ago this month, North Korea and the United States concluded the Agreed Framework. That accord halted North Korea’s nuclear weapons program at Yongbyon in exchange for heavy fuel oil and the eventual provision of two light-water reactors (LWRs) at Kumho, North Korea.
The agreement was the result of prolonged negotiations during a tense period. Unfortunately, its success was temporary. Eventually it became clear that North Korea in the late 1990s was pursuing a clandestine program to enrich uranium for use in nuclear weapons in violation of the Agreed Framework. In October 2002, when an official U.S. delegation confronted the senior North Korean negotiator with this information during talks in Pyongyang, the negotiator admitted that North Korea was pursuing an enrichment program and other unspecified programs.
Subsequent to this admission, North Korean officials maintained that they did not have an enrichment program. They changed their story again in 2010, when they revealed to visiting U.S. nuclear expert Siegfried Hecker that they had an enrichment facility at Yongbyon with 2,000 spinning centrifuges. Hecker was permitted to visit this facility and was impressed with its sophistication.[1] Thus, the issue of North Korea’s clandestine enrichment program was finally put to rest. North Korea proudly admitted having the program, despite its past disclaimers and the skepticism of observers in the United States and China who questioned the U.S. intelligence community’s assessment that North Korea had a clandestine enrichment program for nuclear weapons development

| Summary/Abstract |
In 2007 the five recognized nuclear-weapon states convened for the first time to examine what nuclear transparency and confidence-building measures they could jointly pursue. The P5 process,^sup 1^ as it came to be known, was born in a nuclear policy environment vastly different from the one that prevails today.
It was established as a result of an initiative from the United Kingdom, which was eager to reverse the stagnation it sensed in the nuclear-weapon states' progress toward meeting their disarmament commitments under the nuclear Nonproliferation Treaty (NPT). In June 2007, UK Foreign Secretary Margaret Beckett argued for the need to "engage with other members of the P5 on transparency and confidence-building measures," as well as to involve them in the testing of future verification regimes.

| Summary/Abstract |
Iran’s persistent expansion of its uranium-enrichment program and its covert construction of an underground gas-centrifuge enrichment facility at Fordow have contributed to concerns that Tehran harbors nuclear weapons ambitions. Arrangements for constraining Iran’s ability to use its declared enrichment facilities for nuclear weapons programs are a particularly controversial element in the ongoing multilateral negotiations over Iran’s nuclear program.
Much of the discussion about Iran’s potential production of highly enriched uranium (HEU) for use in nuclear weapons has focused on its three previously secret enrichment facilities that now are under International Atomic Energy Agency (IAEA) safeguards. The concern is that Iran could use these facilities to produce HEU, perhaps after withdrawing them from safeguards.
