“The U.S. is a great government, is a great country. The U.S. did sign the Paris Agreement. It's extremely aggressive to decide on its own just to leave, and no way to push the others to renegotiate because one decided to leave the floor. It doesn't fly. I think it's a big responsibility in front of history, and I'm pretty sure that my friend President Donald Trump will change his mind in the coming months or years. I do hope.”
