The Observer view: Europe must now come of age as a global player | Observer editorial

As Trump upends old alliances, Keir Starmer's collaboration with EU leaders is welcome and should extend beyond defence

Britain and Europe are together facing a watershed moment, a turning point, a second Zeitenwende, a paradigm shift, a new world order. Regardless of which of these overused phrases best describes the dramatic shifts unfolding since Donald Trump began his second US presidential term in January, politicians, diplomats and analysts all agree: nothing will be the same again. The key question now is what, in practical terms, Europe and Britain can and will do to meet this challenge. Is this Europe's moment, when it finally comes of age as a global player? Or will the EU and its close neighbours collectively fail to rise to the occasion, condemning their citizens to an era of domination by bigger, rapacious and more determined powers?

Donald Trump is in the process of attempting, rashly, to do three extraordinary things. First, he is trying to force Ukraine, which has spent more than three years under murderous assault, to accept a peace deal" on inimical terms dictated by himself and the aggressor, Vladimir Putin's Russia. Second, in a stunning reversal of US policy, he is seeking a rapprochement with Moscow that includes re-establishing full political and diplomatic relations, lifting sanctions and launching joint economic partnerships. Third, he is telling Europeans they must henceforth defend themselves, that the US, in effect, is no longer a loyal, reliable partner or even necessarily a friend, and that Nato, for 76 years the solid bedrock of transatlantic security, is dispensable.
