Sika 'dwa: The Golden Stool

The Ashanti have neighbored one of colonies for some time, so far without any major diplomatic incidents. This all changed recently, when our governor, our representative at the Gold Coast, heard of the Golden Stool. This mysterious old artifact apparently holds great significance to the Ashanti, to whom it is the seat of the king. Although we have been vaguely aware of its existence before, it recently came to the knowledge of, who demands to sit on it as a demonstration of his, and by extension our, paramount power in the area. \n\n'Why am I not sitting on the Golden Stool at this moment?' he has asked the Ashanti, who have so far shown no sign of complying. Indeed, they seem highly insulted by the suggestion alone. How far should we be willing to pursue this?
