I would imagine U.S. foreign policy, particularly the prolific use of sanctions contributes to this wane as well. There was some discussion about this a while ago - effectively as the U.S. continues to rely on a strategy of imposing sanctions against foreign adversaries, those adversaries increasingly reorient their economy towards non-U.S. economies such as Russia or China. The more the U.S. utilizes sanctions, the less effective they become.
