Kawano's influence over political decisions rested on persuasion. A Royal Navy officer called him the 'smiling assassin of diplomacy' because counterparts left agreeable meetings only to realize that Kawano had secured every outcome he wanted. His intelligence, friendliness, and skill in international relations made the result feel mutually beneficial. Ship procurement required decisions years ahead of delivery, so securing political support during the difficult budget climate of the 2010s could affect capabilities in the 2020s and 2030s. Kawano helped make those plans familiar enough that elected officials did not feel they were surrendering decision authority. Politicians retained final power over budgets, procurement, and war, while he helped shape their choices alongside the many other contributors to Japanese naval procurement.
