Diplomatic language and the failure to deter Germany over Belgium

Why did Britain not tell Germany more plainly that invading Belgium meant war?

British diplomats did convey the warning, but in diplomatic language the Kaiser discounted; a blunter statement backed by fleet posture might have deterred more effectively.

Britain warned Germany, but the warning failed as deterrence because the participants did not interpret diplomatic language in the same way. British officials assumed the conventions were understood, while Kaiser Wilhelm remained convinced that Britain would stay out. A blunt naval figure such as Jacky Fisher might have paired plain words with visible fleet positioning. The longer exchange describes the Foreign Office as a translator between the British government and other states. That role requires understanding both sides, and it breaks down when officials misread the political culture receiving the message.
