The transatlantic relations, although still solid, appear today less for granted and based on praxis and certainties. Instead of a post-American Europe, it is advisable a growing cooperation between NATO and the EU, in continuity with the "spirit" and substance of the last Joint Declaration adopted on occasion of the Warsaw Summit of July 2016 and the consequent progress made on several programs.
The Alliance has always shown to be able to prevail in the difficult passages the reasons of unity on those of the division, through research of a point of political balance between the various Allied sensibilities. In Warsaw, NATO has shown that it has reached a stage of conscious and appreciable maturity. As far as the future is concerned, it will be crucial, in the Trump era, the "capacity for adaptation" that NATO will continue to demonstrate.
