FEDERICA MOGHERINI:

It is true that, with the United States, we have longstanding friendship, a strong partnership, many things we continue to do together, but also some points of difference, when it comes to some of the foreign policy or security policy approaches that this administration — or President Trump, rather, personally is taking.

And I would like to stress this once again. We are living in dangerous times in the world. For once that we have an agreement that is functioning, that is working, that is delivering, the worst thing you can do is trying to dismantle it, also because you would show the way to others that making deals actually is not worth it, because the message that America would send to the rest of the world is that America cannot be trusted upon, because a deal that America voted for just two years ago in the U.N. Security Council, with a resolution unanimously adopted, a deal that America helped to shape enormously, enormously, would be rejected by the same country.

If we pass the message that every change of administration in Washington or elsewhere, deals are thrown away and renegotiated, no one would negotiate with any administration ever, and any deal would be exposed to be renegotiated every term.

This is not a way of making deals, not in foreign policy, not in private businesses. And I think President Trump understands this perfectly well.
