The Liberal-Democratic Party (LDP) has consistently supported a close alliance with the United States as a cornerstone of its foreign policy, primarily to facilitate Japan's economic recovery and national security following World War II.12
The party’s strategic rationale for this relationship includes:
- Economic Prosperity: The alliance was founded on a quid pro quo arrangement where Japan gained access to U.S. markets, allowing it to expand its foreign trade and develop into an economic superpower while minimizing its own security expenditures.3
- National Security: By maintaining the United States–Japan Security Treaty, the LDP ensured a security umbrella that allowed Japan to focus on domestic growth. In the 21st century, this alliance has evolved to address a more complex security environment, with the LDP strengthening operational integration between the Japan Self-Defense Forces and U.S. forces to counter regional challenges, including those posed by China and North Korea.345
While the LDP has maintained this alliance, it has navigated internal debates regarding the specifics of the security relationship, such as the presence of U.S. military bases and Japan's role in international peacekeeping.6
