Disengaging Russia from the ISS

The International Space Station (ISS) partnership has survived trying times over the years. During my last spaceflight in 2014 to 2015, Russia annexed Crimea, started a civil war in Ukraine, shot down a civilian airliner, and the West imposed sanctions. The ISS was the sole bright spot while relations between the West and Russia sank to their lowest levels since the Cold War — until now.
