What nonsense. The people most worried about no deal are the Germans. You seem be missing much of what's going on around you. Pro-EU is pro-Titanic.
So no, Germans at least are not worried about no deal. I don't think anyone talks much about Brexit in the EU, except for Britain. I don't think anyone is worried at all.
In all fairness, why would anyone outside of Britain even care ? Whether Britain wants to stay or leave the EU with or without a deal is entirely up to them. The rest of the EU or the world doesn't (and shouldn't have) any kind of say on that.
