How did militarism contribute to increased imperialism?

Militarism is the ideology according to which military force is the source of all security. In its mildest form, it is often postulated with very varied arguments, to justify the military preparation of a society, all of which tend to assume that peace through force is the best or only way to achieve peace.

During most of the history the world powers used the military power to settle in different territories around the world, this situation is very clear during imperialism.
