Crown Prince of Saudi Arabia, Mohammed bin Salman (known as MBS), at only 34 years old, leads a state in Western Asia with immense oil reserves that significantly impact the global economy. This country is also home to Islam's holiest sites and remains the world's largest arms buyer. Accused of orchestrating the brutal assassination of a journalist and the kidnapping of a foreign Prime Minister, engaged in a bloody war in Yemen, and determined to counter Iran at all costs, MBS is also a key partner in the fight against terrorism and is implementing spectacular reforms that are reshaping his kingdom.
