What was the african saying that theodore roosevelt often used? how do you think it applies to the issues of expansionism and imperialism?

The African saying was "Speak softly and carry a big stick". This, in the terms of expansionism and imperialism, means that they would give to-be- 'colonies' a chance to accept US control. If they fail to meet the requirement and prove to be a threat to the US, the US would then use it's "big stick", or the military, to crush the rebellion/threat

hope this helps
