Beijing flexes nuclear muscle, sends signal to US

China tested an intercontinental ballistic missile in international waters for the first time in 44 years on Wednesday, an unusual move that analysts believe is intended to send a signal to geopolitical rivals. Namely: Don’t mess with our security, because we can defend ourselves with nukes.

Building the bomb, tickling the dragon

“Tickling the dragon’s tail.” That’s how the small group of physicists working at Los Alamos in the 1940s under the watch of Robert Oppenheimer described the dangerous job of assembling a nuclear core for the first atomic bomb. One wrong move and a chain nuclear reaction — the dragon — could have wiped them all out.

Nuclear nonproliferation has worked so far, but watch out for those questioning it — arms control expert

Nuclear nonproliferation treaties have been a success at stopping the atomic club from growing further by discouraging new membership, but nuclear arms control expert Kelsey Davenport says the slow pace of disarmament "is causing some states to begin to question that bargain." Although it's unlikely that nuke-curious countries will actually get the bomb because it costs too much time, money and resources, Davenport told Ian Bremmer on GZERO World that she believes that simply questioning the benefits of nonproliferation creates a real risk that must be "monitored and mitigated."

Nuclear weapons: more dangerous than ever?

In recent years, as nuclear disarmament worldwide has slowed to a crawl, world powers are engaging in a new kind of arms race: a technological one. Today's nuclear threat is not about who has the most nukes, it's about who has the smartest ones. Arms control expert Kelsey Davenport joins Ian Bremmer on GZERO World to talk about the world's long fascination with these horrible weapons and how close we still remain to all-out nuclear war.

The new nuclear arms race: Smarter, faster nukes

There's a lot of talk about nukes these days — but not about Cold War-era massive arsenals and mutually assured destruction. Nuclear weapons expert Kelsey Davenport says the risk of something going horribly wrong is rising because countries like China or Russia are developing smaller warheads and high-tech delivery systems such as hypersonic missiles, which traditional arms control agreements don't take into account. Watch her interview with Ian Bremmer on the upcoming episode of GZERO World.
