Pettit and his colleague Paul Strefling, sitting in the pilot’s seat between us, are engineers in the business of ride quality. Their job is to program the movable parts on an airplane’s tail and wings—the rudder, elevators, and nearly two dozen ailerons, flaperons, and spoilers—to smooth out its flight automatically when turbulence hits. To get data for the simulator, their team takes full-size Boeing jets on research flights over the Rocky Mountains. They hunt for rough air, then loop through it again and again, like race-car drivers on a test track. They record every flutter and quake using the plane’s sensors, then download them to the simulator’s computers. The flight deck we were in could be swapped with one from a 737 or a 787, and the turbulence reprogrammed for the size and shape of those planes. Then, with the flip of a switch in the control room next door, the cab would start to shake and roll on its piston legs, as if having a seizure.
特朗普第二任期延续了第一任期及乔治·W·布什政府给国际秩序带来的深刻破坏。布什政府通过政治化情报发动伊拉克战争，令美国盟友深陷冲突，并加剧了与“老欧洲”的对立。尽管两者在风格上有所不同，但放在一起审视便能识别出一种明显的模式：美国不再是值得信任的全球领导者，它无法通过规范、制度或自我约束为国际社会提供稳定的行为模式。
