I want to know the answer to the following question:
Why do nations risk significant political impacts if a carrier is lost or even used in conflict?
All the background I'm provided with is that "The large, modern Nimitz class of US carriers has a displacement nearly four times that of the World War II–era USS Enterprise, yet its complement of aircraft is roughly the same—a consequence of the steadily increasing size and weight of military aircraft over the years.". Is that enough to answer the question?
Answer: no
