Asia & the Pacific

The summit between President Trump and North Korea's Kim Jong Un in Hanoi, Vietnam, ended Thursday without any deal. The two sides failed to reach an agreement due to a standoff over U.S. sanctions on the reclusive nation.

Michael Beckley explains how power can be measured more accurately by calculating a country’s net resources.

All the world's nuclear-armed states (except for North Korea) have begun modernizing and upgrading their arsenals, leading many observers to predict that the world is entering a new nuclear arms race. While that outcome is not yet inevitable, it is likely, and if it happens, the new nuclear arms race will be different and more dangerous than the one we remember. More nuclear-armed countries in total, and three competing great powers rather than two, will make the competition more complex. Meanwhile, new non-nuclear weapon technologies — such as ballistic missile defense, anti-satellite weapons, and precision-strike missile technology — will make nuclear deterrence relationships that were once somewhat stable less so.

Nuclear weapons remain the most powerful weapons on the planet and how President Donald Trump’s team manages nuclear issues is critical to our security. These are hard challenges; none were perfectly addressed under President Obama’s leadership. But we made them a priority from day one. Whether or not the new team puts them at the top of the to-do list, here are five issues that will demand their attention before too long.
