North Korea's third successful nuclear test has been widely condemned by the international community. CFR's Paul Stares highlights three things to know about the test and its implications for nuclear nonproliferation.

Secretary John Kerry and United Nations Secretary-General Ban Ki-moon gave these remarks before their meeting on February 14, 2013. They outlined the main issues they would discuss: North Korea's nuclear test and Six Party Talks, negotiations with Iran, the crisis in Syria, and France's intervention in Mali.

The UN Security Council passed this resolution regarding North Korea and ballistic missile technology on January 22, 2013.

Hyun In-taek and Kim Tae-young discuss their experiences managing crises on the Korean peninsula in 2010 and their policy recommendations for future U.S.-ROK cooperation.

This U.N. Security Council Presidential Statement on North Korea was released on April 16, 2012.

Experts provide an update on North Korea, including its relationships with South Korea, China, and the United States.

"North Korea's impending nuclear test is just the latest illustration of Barack Obama's weakness and naiveté abroad," writes special advisor to Mitt Romney's presidential campaign, Richard Williamson, who served in the Reagan White House as an assistant to the president in the 1980s and as the president's special envoy to Sudan in the 2000s.

In his testimony before the House Foreign Affairs Committee, Scott Snyder argues that the United States should redouble its efforts to shape North Korea's strategic environment rather than try to identify the right combination of carrots and sticks to be used in a negotiation with Pyongyang.

Pyongyang's unsuccessful missile launch delays a new nuclear threat but raises disturbing prospects for violence on the Korean Peninsula, says CFR President Richard N. Haass.

Leslie H. Gelb says military confrontations loom for President Obama in Iran, Syria, and North Korea, and he can't head them off with the usual duet of threats and talks.

Leslie H. Gelb argues that the world is distracted, and North Korea, South Korea, and the United States are stumbling, once again, toward a nuclear confrontation.

A planned satellite launch by North Korea has suspended U.S. food aid. CFR's Scott Snyder says that Pyongyang is grappling with whether to choose international legitimacy or domestic political consolidation.

The Seoul summit advances global efforts on securing nuclear materials in dozens of countries, but the challenge will be to sustain the focus on the universal elimination of weapons-usable material, writes CFR's Micah Zenko.

Heads of fifty nations are discussing how to improve safeguards for nuclear weapons and materials. CFR's Michael Levi says these summits serve as reminders of the dangers beyond the North Korean and Iranian nuclear programs.

North Korea may be on the verge of a "transformative moment," which will require the time, attention, and resources of the winner of the U.S. presidential election, says CFR's Scott Snyder.

North Korea's agreement to freeze nuclear activities and allow in inspectors, while stirring hopes, echoes past deals that have failed to initiate a sustained denuclearization program, says expert Mark E. Manyin.

U.S. State Department Spokesperson Victoria Nuland gave this statement on February 29, 2012 regarding U.S.-North Korea bilateral talks and North Korea's agreement to implement a moratorium on nuclear activities including uranium enrichment.

North Korea's decision to suspend nuclear tests in exchange for U.S. food aid may pave the way for resumption of the Six-Party Talks on denuclearization, but it's unlikely to yield significant progress, says CFR's Scott Snyder.

The Six-Party Talks serve as a forum about North Korea's nuclear weapons program, but the negotiations have been riddled by Pyongyang's belligerence and the differing priorities of the participating nations.

This week's meeting between U.S., South Korean, and Japanese officials signaled an opening for North Korea to rejoin the suspended talks on its nuclear program. CFR's Scott Snyder discusses the talks and says it's unlikely the dialogue will resume soon.
