Brexit as a unified strategy to remain under some laws of the European Union and other enforcement by EU commission.

metaphor that describes an event that comes as a surprise, has a major effect, and is often inappropriately rationalized after the fact with the benefit of hindsight. The term is based on an ancient saying which presumed black swans did not exist, but the saying was rewritten after black swans were discovered in the wild.

The theory was developed by Nassim Nicholas Taleb to explain:

The disproportionate role of high-profile, hard-to-predict, and rare events that are beyond the realm of normal expectations in history, science, finance, and technology.
The non-computability of the probability of the consequential rare events using scientific methods (owing to the very nature of small probabilities).
The psychological biases which blind people, both individually and collectively, to uncertainty and to a rare event's massive role in historical affairs.
Examples: The Internet, The dissolution of the Soviet Union. The internet has had globally disrupting ripples of effect which are ever impacting in the present and in the future including; blockchains, taxing robots, social costs (negative externalities).

Without looking critically at the past, our own wars and others, all of the arguments about AirSea Battle, disruptive technologies, and offset strategies will be largely premature, if not largely uninformed.https://warontherocks.com/2015/08/black-swans-and-pink-flamingos-five-principles-for-force-design/ Richard Danzig’s widely cited CNAS paper, Driving in the Dark, recommended that the “defense community should also design processes, programs and equipment on the premise that predictions will often be incorrect. While trying better to illuminate the road, analysts should recognize that sudden twists and turns in areas of darkness demand special driving techniques.” Danzig’s driving metaphor is appropriate for steering into a future that, by its nature, is uncertain. From that metaphor I have derived a set of five force planning principles:

BLACK BREXIT Such a compromise is midway between a “black Brexit”, a cliff-edge scenario for businesses and financial services in which the government left the article 50 talks without a future deal with the EU, and a “white Brexit”, which would see the UK attempt to remain in the single market.

Structural breaks render obsolete many existing patterns of behavior, yet they point the way forward for some companies and at times even for whole economies. The Long Depression of 1893–97 marked the end of the railroad boom, for example, and the start of the transition to an economy based on sophisticated consumer goods. Milton Hershey built his early chocolate brand and distribution advantages in the middle of those hard times. General Electric was a product of the same period, for the structural break also marked the rise of a new economy based on electricity.
