The performance of the president of the United States in Europe over the past week left Europeans dumbfounded, shaken and at least on trade, rightfully anxious about the future. Donald Trump has once again threatened Europeans with tariffs in the one sector that hurts (Germans especially) the most — the automotive industry. Since his election, America's new protectionism certainly makes Europeans feel isolated on issues of trade and the defense of liberal values.

Yet what Europeans often forget is that this is not the case. Europe is not the last man standing. Japan, Australia, India and Canada are all still very much part of our community of shared values.

How we strengthen this community, will depend on the way Europeans will capitalize on the visit of Jean-Claude Juncker and Donald Tusk to Tokyo this week. This visit can take two different paths. One is the path of diplomatic niceties, signing agreements, and smiling and posing for pictures. Following the storm caused by Trump in Brussels and London, that was a welcome respite, to be sure. The other path goes far beyond and can turn our relationship into something much more enduring and ambitious.
