Arms Control Twitter has been abuzz since the August 20 announcement that the United States had conducted a surprise launch of a Tomahawk missile days before on August 18, 2019.
This wasn’t just your regular missile launch, however. It was a Tomahawk cruise missile launched from a ground-based Mark-41 Vertical Launch System (VLS), traveling to a distance of “more than 500 kilometers,” according to the Department of Defense.
In other words: A violation of the Intermediate-Range Nuclear Forces (INF) Treaty––if the treaty still existed. It officially died on August 2nd, six months after both the United States and Russia announced suspensions of their respective treaty obligations. But the launch is an important walk-back of US security policy which for 32 years sought to curtail such weapons and instead, as we have written for the Bulletin of the Atomic Scientists, makes the United States needlessly complicit in the INF’s demise and frees Russia from both the responsibility and pressure to return to compliance.
