An especially bad aspect of Joe Biden’s foreign policy was how it drove disparate countries in the international system together to oppose the United States. In short, Washington’s arrogant bullying intensified disruptive behavior on the part of longtime adversaries and created new enemies in the ranks of previously neutral powers.
