" We have to remind ourselves of where we want to get to here, and where we want to get to is a good trading relationship between the EU and the US, and we don't want to be in a tariff environment, but obviously Europe has to show a willingness to act should the Trump administration refuse to come to the negotiating table in a real and substantive way".
