Iran is blaming Israel for the assassination, but its response has been restrained. It doesn’t want to provoke Trump into launching a last-minute attack on its nuclear facilities. But the guns are locked and loaded. When will the shooting begin?

U.S. return to the Iran nuclear deal could be difficult. Much has changed in the world in the past four years, including the recent assassination of Iran’s top nuclear scientist. China’s help may be needed more than ever.

Emerging technologies are bringing advanced capabilities to more countries and adding new ambiguities, which only increase risk. Failing to strengthen controls now will lead to a new arms race.

Any resolution of the nuclear issue must start with the recognition of the DPRK’s deep concerns. While the six-party talks have not yet resumed and risks remain, China will remain critical to the future outcome.

With China, Russia and the U.S. all developing major space programs, trilateral accords and communication will be key to avoiding misunderstandings – or war – between nations.

Cooperating over North Korea is essential for both China and the U.S. – not just for the good of the DPRK, but for the Sino-American relationship at large.

China did not take the route of the United States and Soviet Union in the Cold War era but held to a rational, reasonable policy. Barring some major international shift, it’s a posture that’s not likely to change soon.

A popular view in China is that more nuclear weapons would garner respect from the international community. But it may only inspire fear, which would be counterproductive.

Although bilateral cooperation between China and the U.S. is sub-optimal at this moment, Beijing and Washington must not overlook other global challenges such as nuclear non-proliferation and arms control.

India and China’s nuclear deterrence allows both countries to undertake bilateral problem solving without fear of conflict escalation, while the United States and China can simultaneously work to reduce overall global nuclear risks.
