Hmmm have a think what you would do if someone you ' d trusted suddenly betrayed 40 years of bilateral trade agreements without at least respecting the rules of disengagement , do you think you might react and in one way or another cut them off ? If that where to happen all the things ' they ' where trading would have to be supplied by someone else but luckily , we have a block of 27 other just as developed countries with incredible connections and the most advanced trading agreement in the world ready to take up the slack . We maybe a good customer of theirs but they are overall a much more important customer of ours . This article is a good example of why people don ' t trust brexit thinking , they seem to not take into account that the EU is full of people capable of thinking and reacting in exactly the same way as they would , it just doesn ' t seem to add up . It keeps reminding me of the way people said it ' ll be all over by Christmas before WW 1 .
