Over 100 days into the Biden administration, how have transatlantic relations shifted? This policy brief builds upon analysis from an October 2020 piece titled “No going back? A transatlantic cooperation agenda under Biden” and examines lessons for European policymakers from the first few months of Joe Biden’s presidency. Knudsen argues that while Biden has retained many core parts of Donald Trump’s “America First” agenda, there are still several promising avenues for transatlantic cooperation over the coming years. These include accelerated climate action, coordinated economic stimulus, and ensuring global vaccine access. Reaching these goals will require joint action to defuse geopolitical tensions and ensure greater economic justice at home and abroad.
