Did the United States use Hood's great size to force down the Royal Navy at the Washington Naval Treaty?
Short answerNot in that simple form; Britain knowingly accepted limits to save money and cultivate American goodwill under its own strategic assumptions.
NotesThe United States did not simply weaponize Hood's size to shrink the Royal Navy. British ministers entered the negotiations with their eyes open and accepted risk under the Ten Year Rule. They wanted to reduce costs while preserving American goodwill. Their calculation aimed for a friendly neutral United States if Britain entered another major war, even at the price of limits on British naval strength.
