Russiaâs threat of war with Ukraine, whether for real, for show, or for some undetermined mix of the two, demands a powerful response. While the military-strategic aspect has to be left to the US/NATO, the EU can respond on the basis of its own capabilities in three ways. First, it can invest urgently in phasing out its reliance on Russian gas by diversifying supplies and increasing its strategic reserves, with Germany to make a first contribution by stopping Nord Stream 2. Second, the EU can demonstrably support Ukraine by advancing its integration with the EU in ways that can be readily identified. Third, it can supply Ukraine with large amounts of Covid-19 vaccines, which are desperately needed to boost recovery from the pandemic â as a humanitarian and geopolitical imperative for both parties.
