This introduction presents an overview of the key concepts discussed in the subsequent chapters of this book. The book President Barack Obama addressed world leaders at the opening session of the United Nations General Assembly in New York City, just a few miles from where the Twin Towers had been brought down on that fateful morning. Again Obama noted that the end of the Iraq conflict reflected a broader US military disengagement, and he proclaimed that "the tide of war is receding" as Qaddafi's death marked the imminent closure of NATO operations in Libya and troop withdrawals from Afghanistan would soon mean a transition to Afghan leadership. Even a compelling and resonant presidential narrative will not be successful, Entman emphasizes, it is made easily available to vast numbers of citizens and individuals deign to take notice. A frame therefore achieves what he terms magnitude through prominent placement in the mass media and frequent repetition of the framing words and images.
