@sigbert Mir ist nicht ganz klar, wie das gemeint war:
At the gathering of the Conservative Way Forward, a Thatcherite campaign group, he said exit talks were approaching a “moment of truth”. The foreign secretary said he believed Brexit will happen and would be “irreversible” but the “risk is that it will not be the one we want”.
In comments captured in a recording obtained by BuzzFeed News, he said Theresa May was “going to go into a phase where we are much more combative with Brussels”. He added: “You’ve got to face the fact there may now be a meltdown. OK? I don’t want anybody to panic during the meltdown. No panic. Pro bono publico, no bloody panic. It’s going to be all right in the end.”

Auch Barnier hat es eher als Drohung verstanden:
In response to Johnson, who had suggested in leaked comments that a “meltdown” in the talks was coming and that the UK could benefit from the assertive negotiating style of Donald Trump, Barnier said: “I always listen very attentively to what he says and it is always very stimulating. But I am not going to comment on that.”
Barnier said he would not be intimidated by UK politicians. “If we want to build a new relationship, we need a base of trust, we also need more realism about what is and what will be possible and what is not.”
