With their decision to launch an impeachment inquiry of President Donald Trump, congressional Democrats have embarked on a step that will have profound implications both for American domestic and foreign policy. Much of the media discussion about the Trump impeachment inquiry has centered on handicapping this latest phase in the political battle between Republicans and Democrats to retain or regain the presidency.

The impact of Watergate, for instance, was anything but trivial. Arms-control efforts with the Soviet Union collapsed. An ignominious retreat from Vietnam took place, OPEC was emboldened. In short, the consequences were grave as American credibility around the world was tarnished.

But beyond affecting the particulars of specific American policies toward allies and adversaries, the impeachment saga may have a more lasting effect on the process of foreign policymaking itself. The...
