Since the inauguration of the Trump administration, the United States appears to have abdicated from a role it has fulfilled since the end of World War II — namely, that of defender of the liberal international order. For example:

The U.S. is forcing Mexico and Canada to renegotiate the North America Free Trade Agreement to the detriment of the pact.

The administration has expressly stated that the U.S. will never again return to the Trans-Pacific Partnership.
