The book "The Key to Understanding Donald J. Trump" tries to get beyond the smokescreen, and to understand the behavior of Donald Trump, which sometimes seems to elusive - having neither pattern nor order. Whether you are a fan or a foe of the president, a political amateur or just an average person who tries to understand whether there is logic to Trump's chaos - the book gives you a window into the brain of the world's most important man and an opportunity to read his thoughts in a way that will allow you to feel that you too can explain the rationale behind his actions, be it at the dinner table, in a conversation with friends or simply when reading the daily news.
