Step-by-step explanation:
Campbell is called the "Indo-Pacific czar" because of the major shift in U.S. foreign policy towards Asia in recent years. This title reflects Campbell's role in leading and coordinating U.S. efforts in the Indo-Pacific region as the deputy secretary of state. The term "czar" is used metaphorically to indicate Campbell's influential and authoritative position in shaping U.S. policy in the region.
Since the U.S. recognizes the increasing importance of Asia in terms of trade and geopolitical influence, Campbell's position acknowledges the significance of this region and emphasizes the need for strategic coordination and engagement. By referring to Campbell as the "Indo-Pacific czar," it highlights his role in promoting U.S. interests and partnerships across the Indo-Pacific region.
