Three phase plan 

A plan to phase out enemies or people that bother you in three phases.

The three phase plan sounds good, but scientists, government officials, and the healthcare workers that like hearing how heroic they are seem to be the ones who actually think it's a good plan. Nobody is telling dentists, pharmacists, chiropractors, proctologists, gynecologists, or pediatricians they're heroes or saviors, since at a certain point it would all start to sound silly.
