Final answer:
A 'deliberate policy' is a carefully planned and executed strategy by a government or authority to achieve a specific goal, seen in historical examples like Lebensraum or Manifest Destiny.
Step-by-step explanation:
The term "deliberate policy" refers to a course of action intentionally designed and implemented by a government or organization with a specific purpose or objective in mind. In historical contexts, such policies have been used to shape territories, populations, and political strategies. Various examples illustrate this, such as the policies of Lebensraum by Nazi Germany, the U.S. philosophy of Manifest Destiny, and Japan's expansion in Asia. These policies were not random but rather carefully planned with the aim of achieving certain goals, whether it be territorial expansion, economic development, or maintaining a conflict for specific purposes, as mentioned in the initial query regarding "flower wars".
