Mark Tooley wrote an article at Providence: The Journal of Christianity and Foreign Policy asserting that National Conservatism and American Exceptionalism are at odds. His example was the U.S. commitment to individual human rights such as religious liberty.
Tooley wrote, “That the USA should as policy promote religious freedom and human rights is intrinsically American Exceptionalism and presumes American principles are morally universal.”
I’m not sure National Conservatism would think promoting religious freedom is a bad thing.
One can make a case for promoting human rights—promoting religious liberty—without engaging in messianic wars to spread democracy or enforce our values on other peoples.
