Switzerland maybe?
you remember Hitler? and appeasement? I don't think we will be able to change their minds about us, David.
Diplomacy doesn''t mean appeasement. It's helpful to talk to people first hand to find out what they want instead of having experts try to guess what they want. Knowing what they want doesn't mean they'll necessarily get it, or we'll want to give it to them. The point of diplomacy is to know your adversary.
If something can be worked out that's fine. But it's not always possible. But people usually come away knowing better what they're up against.
