Some seem to have strange interpretations of things.
No deal is nothing like the equivalent of us shooting ourselves in the head and the EU shooting themselves in the foot. It's simply the only remaining option when the EU is determined to use the tactic of forcing us not to go by refusing to agree to sensible suggestions. In reality it causes an economic blip to both, and maybe further afield too.
No-deal was never simply a bargaining chip, but it had to be made clear to the public (or at least those that claimed not to realise) it's removal left us at the mercy of the EU. Something remoaners seemed to be hoping for. No-deal is simply the default exit if nothing better can be agreed in the allotted time, and the EU was determined nothing would be. The EU needs to know their attempt to force us to remain by threatening no-deal won't work, and they are bringing it on themselves.
