In Robert D. Kaplan's "Earning the Rockies," the concept of grand strategy is explored as a crucial aspect of national planning. It involves aligning a nation’s objectives with the available resources and capabilities. This relationship is essential for creating effective strategies that can navigate the complexities of international relations.

Kaplan emphasizes that successful grand strategy is not just about ambitious goals but also about making practical decisions based on what a nation can realistically achieve. This balance is vital for ensuring that a country can effectively respond to challenges while leveraging its strengths and resources.
