Don’t Scapegoat China for Killing the INF Treaty. Ask it to Join.

, China project manager and senior analyst

September 23, 2016: Chinese UN Representative Liu Jieyi votes in favor of a UN Security Council resolution on the 20th anniversary of the signing of the Comprehensive Test Ban Treaty (CTBT) urging all parties to push for the treaty’s entry into force.

The Trump administration recently announced it intends to walk away from an important agreement that reduces the risk of nuclear war—the INF Treaty. US officials said concerns about China were an important factor in deciding to scrap a nuclear arms control pact intended to last in perpetuity. But there is no evidence the Trump administration consulted Chinese leaders about its plans to withdraw or the concerns that supposedly made it necessary. Read more >

The Demise of the INF Treaty is Dangerous

, analyst

On February 1st, the Trump administration announced that the United States will withdraw from the Intermediate-range Nuclear Forces (INF) Treaty with Russia. The next day, Russia responded by doing the same. These withdrawals will take effect in six months, if nothing is done to save the treaty.

This course of events was no surprise, since President Trump has been threatening withdrawal for months, but the lack of surprise makes the decision no more welcome and no less dangerous. Withdrawal from the treaty undermines the security of the United States and its allies, and opens the door to a new era of arms racing, threatening US-Russian nuclear stability. Read more >

Translation: The Last “Celestial Empire”—Mao Zedong. Kim Il-sung and China-North Korea Relations”

US analysts and officials often refer to North Korea as China’s ally, as if it were a diplomatic or military asset. History suggests it’s more like a rock around China’s neck. Chinese President Xi Jinping may find it too heavy to bear.

Or, he may succeed in solving one of the most intractable security problems in East Asia. The denuclearization of North Korea is the UN benchmark both Xi and North Korean leader Kim Jong-un agreed to meet. They reiterated that promise in their most recent get together in Beijing earlier this month. Read more >

Okinawa’s Burden

China isn’t the only country tearing up precious coral reefs to build new military outposts in the Pacific. Just before the new year holiday, in order to fulfill obligations to the US military, Japanese Prime Minister Shinzo Abe began covering the coral reefs of Henoko Bay with landfill.

It’s the latest move in a decades old struggle between the people of Okinawa, who don’t want another US military base on their tiny island, and the central government of Japan, which agreed to construct the massive new Henoko facility under the terms of a controversial agreement with the United States. US military bases already occupy nearly a quarter of the 466 sq. mi island, which is home to approximately 1.5 million people. Three quarters of all US military bases in Japan and over half of the US military personnel stationed in Japan are concentrated in Okinawa, which accounts for less than 1% of Japan’s total land mass.  Read more >

Memo to Congress: America Already Has Low-yield Nuclear Warheads

, co-director and senior scientist

The Trump administration plans to build new “low-yield” nuclear weapons that would be launched from Trident submarines. Its rationale? It insists they are needed to counter Russia’s low-yield weapons.

This plan has resulted in a lot of confused—or perhaps deceptive—verbiage on the part of some of our elected officials. They seem not to know or neglect to mention that the United States already deploys a wide array of low-yield nuclear weapons.

Or it could be that they have their own set of alternate facts? Read more >
