Bodies do not "benefit" from fever. A fever is a signal that pathogens have recently entered the body, and the body is desperately at work trying to kick them out again. If it fails, you die. The fever is a direct mirror of the inflammation caused by that fight.

So, yes, the current administration certainly caused a fever. And the only thing the US benefits from are the antibodies fighting that pathogen.
