William C. Martel concludes his series, highlighting the lack of a cohesive US grand strategy, with this summary:
A strategic weakness with American foreign policy is the deep and enduring political polarization in Washington that complicates, and often paralyzes, U.S. policymaking. While the United States once conducted its foreign policy on a bipartisan basis, we now see divisions on virtually all issues. Washington’s failure to move beyond this polarized environment puts at risk its ability to act with one voice on foreign policy. Essentially, it puts at risk the entire enterprise of grand strategy because a deeply divided nation cannot implement its resources and interests effectively.
By definition, American grand strategy demands that policymakers and politicians take the long view. While it is an enduring challenge for policymakers in Washington to look beyond the next election, the nation has no choice. It must build a grand strategy that addresses how the United States deals with the future that extends beyond the coming months or years. Abroad, the nation must work with other states and institutions to shape the secure international order that all states desperately need. The alternative is a world marked by uncertainty, fear, and strife.
