Gunboat diplomacy

Gunboat diplomacy when you park a dirty great warship in somebody's harbour and say, "we'll be nice to you, just give us what we want." Then they say, "why should we?". You say, "You see this big warship here? It's a surprise tool that may help us later". This method has been used by Humerland against Omari Robusuta. It has also, not very successfully against Fictia by Omari Robusuta.
