As a seasoned communications professional, I believe in the power of ideas to change the world. Yet, I am often reminded of the limitations of my field, as every day brings a new cautionary tale of hype and hubris. No lesson is more timely than Britain’s exit, or “Brexit,” from the European Union. As Prime Minister Theresa May seeks to convince her party and the nation that she is delivering the European divorce that she promised at the beginning of her term, she is struggling to live up to her own spin. This is a classic tale of tactics winning out over strategy.
