A number of important elements for the future of transatlantic relations have emerged from the packed agenda of international summits staged in the last few days (G20, NATO anniversary, EU-USA summit). On the one hand, Obama’s first trip to Europe has evidenced the magnitude of the European partners’ expectations regarding the new US administration. On the other, the tight string of summits has shown, as never before, the need to consider the relations between the issues discussed at the different meetings. Seen in this light, the celebratory summit for the sixtieth anniversary of NATO takes on a broader significance. In spite of the desire to re-launch the Atlantic partnership after the differences of the Bush era, the future of the Alliance – increasingly a function of USA-EU consensus – can still not be taken for granted. The EU is now being called upon as a matter of urgency to shows its ally the added value of its contribution and the ongoing utility of NATO regarding a series of items; from development of capacity to burden sharing in Afghanistan, the formulation of a new strategic doctrine and the problematic dialogue with Russia. Otherwise, for the EU there is the risk that inability to follow up the points of cooperation with facts, will be transformed into a future marked by progressive isolation.
