So long as we are all in the same sinking boat, we would be wise to focus on rowing in the same direction.
And in the text of the editorial there's this:
Comrades, we are in the same boat. A sinking one.
Guardian readers, it seems, feel comfortable referring to each other as "comrades" - something which conjures up images of communist commissars from the USSR.
Will the EU go the same way as the USSR and collapse? It's certainly possible, but we shouldn't be too hopeful. The European elite believe in the EU as a moral cause and won't let go of it unless they really have to.
