Submitted for your disapproval, a mad scenario of epic nuclear devastation by the Time Ghost history team on YouTube. Aside from turning Paris into a smoking crater, take a look at Nukemap and see what various sizes of nuclear bombs would do to your city/town/region. I "dropped" a 1 Megaton Nuke on/over Ford Island at Pearl Harbor and witnessed the end of Honolulu in a flash. Since I live some miles from Honolulu, the book, "Alas Babylon" came to mind.
