Henry had a simple model of geopolitical progress: You try to figure out what the other side wants, understand its motivations and pain points, and then find something that is possible and that it will see as an improvement. He was a fearsome negotiator with an impressive grasp of other countries’ history and an ability to assess their leaders realistically and to think three moves ahead. He viewed American culture as not strategic in this way: We tend to approach adversaries with a list of demands when we should have a conversation about a stable long-term outcome.
Grand strategy in his mind was exactly that. The exploitation of the Sino-Soviet split was a natural outgrowth of this approach.
