I resigned because the traditional core values of the United States, as manifested in the president’s National Security Strategy and his foreign policies, have been warped and betrayed. I could no longer represent him personally and remain faithful to my beliefs about what makes America truly great.

The amateurish promulgation of a country-specific travel ban, the push to build a “big, beautiful wall” and to expel the “dreamers” beyond it, the withdrawal from the Paris climate accord and the Trans-Pacific Partnership, and the belligerent renegotiating of the North American Free Trade Agreement and counterproductive steel and aluminum tariffs are all making the United States weaker and less prosperous. America is undoubtedly less welcome in the world today, as the president pursues a unilateral and isolationist path.

These policies are purportedly being pursued to make good on nativist campaign rhetoric that resonated with many legitimately aggrieved Americans. But I know many of these voters.
