As the coronavirus pandemic continues to spread across Europe, the United States has reduced its participation in a Nato military exercise that was set to be one of the alliance’s largest since the end of the Cold War. In April and May, the Defender-Europe 20 exercise was meant to feature 37,000 troops from 18 countries, including 20,000 soldiers deployed from the United States. It was planned to take place across ten European countries, with the bulk of the drills in Germany, Poland, and the Baltic states. Shortly after the WHO declared that Europe had become the new ‘epicentre of the pandemic’, the Trump administration enacted a travel ban for foreign visitors from the 26 countries in Europe’s Schengen travel zone, and then from the UK and Ireland.
