This may be the most important moment for our transatlantic alliance since the end of the cold war. Terrorist attacks inspired or directed by Isis have slaughtered innocents in Nato countries, from Orlando to Paris to Brussels to Istanbul. Conflicts from Africa to Syria to Afghanistan have sent waves of migrants seeking refuge in Europe. Russia’s aggression against Ukraine threatens our vision of a Europe that is whole, free and at peace. The vote in the UK to leave the EU raises significant questions about the future of European integration.
As I arrive in Warsaw for meetings with Nato and EU leaders, I believe that our nations must summon the political will, and make concrete commitments, to meet these urgent challenges. I believe we can — but only if we stand united as true allies and partners.
As difficult as it will be, I am confident that the UK and the EU will be able to agree on an orderly transition to a new relationship, as all our countries stay focused on ensuring financial stability and growing the global economy. And, while the relationship between the UK and the EU will change, it is worth remembering what will not change.
