The ill-advised war in Iran has commenced. Mark Weber, Director of the Institute for Historical Review, provides a clear and composed perspective on Trump’s fateful decision, including background, consequences, and possible outcomes. An accomplished historian, lecturer, and current-affairs analyst, Weber is unusually well-informed about Iranian relations with other countries, including the United States, as well as about twentieth-century Iranian history. During his three visits to Iran, Weber met and spoke with a wide range of people, including ordinary citizens, writers, scholars, activists, and government officials from various countries. He has addressed meetings in Tehran, including a lecture to hundreds of young Iranian university students, and spoke at a conference of government leaders, where the country’s president also spoke. Weber’s expert opinion and commentary on this matter of utmost importance needs to be heard by all.
