Claiming to be able to make massive cuts without cutting national defense, Social Security/Medicare, or loads of basic government stuff (like the U.S. Mint, patent office, passport services, etc.) is how you know this will never happen.
Every conservative comes to Washington ready to cut whole departments and then learns the Department of Energy manages the nuclear weapons stockpile and the entire National Park system is a rounding error on a B-2 bomber order.
If you ask a historian “How would you assess Winston Churchill?” and they criticize the concept of fighting fascism and not, like, the Bengal famine, strategic decisions, imperialism, drinking up all the gin, etc. then maybe you aren’t talking to an actual historian.
