Re pacifying 27 countries:
We were in a large trading bloc with them. If you think of nations like shops, we had a nice big outlet in the world's second-biggest mall.
We're giving up that store. We're going to set up shop in the high street, by ourselves.
This means we're now in competition with the malls.
Not only do we have to attract customers who mostly drive to the big malls, but we've also got to do deals with all the suppliers. Instead of getting the group discounts, we've got to set up our own contracts. We're no longer one of their biggest customers so we may have to go with little start-ups who are desperate for the work.
Customer-wise, we can't compete with the variety of the EU mall so we have to get people to go out of their way. Probably by being either a specialist shop doing stuff the mall stores don't, or be a pound shop.
The chart shows GDP, so in this metaphor it's ranked by takings. The malls are China, EU, US, and there's our little store further down in green.
