The Role of U.S. Bases in Southeast Asia: Aggression or Stability?

Follow @SkillsGapTrain

The presence of U.S. military bases in Southeast Asia is often criticized as a form of aggression or containment aimed at China. However, a closer analysis reveals that these bases serve multiple critical functions, rooted in historical precedents, geopolitical realities, and the need for stability in a region marked by economic and strategic significance.

Historical Context: Lessons from Romania

Over the last 2000 years, Romania and its predecessor states (Dacia, Wallachia, Moldavia, and Transylvania) have faced approximately 50 major wars initiated by foreign powers. These included invasions by the Roman Empire, Mongol raids, Ottoman expansions, and conflicts with neighbouring powers like the Habsburgs and Russians. Romania’s strategic location made it a frequent target for more powerful empires, with most conflicts being defensive. This history underscores the challenges smaller nations face when caught between larger powers, a dynamic mirrored in Southeast Asia today.

Much like Romania historically relied on alliances to balance the power of stronger neighbours, the U.S. presence in Southeast Asia helps smaller nations counterbalance China’s dominance.

1. Defending Smaller Allies

Southeast Asia comprises nations like South Korea, the Philippines, Taiwan, and Japan, which are significantly smaller and less militarily powerful than China. These nations often lack the ability to independently deter aggression from larger powers. U.S. bases provide:

Security Guarantees: Ensuring that smaller nations can negotiate and act as equals without being coerced by China.
Power Parity: Establishing a balancing force to maintain peace and prevent domination by any single regional power.

Without these bases, smaller nations would be vulnerable to coercion or military action, similar to how Romania suffered from invasions and occupations without strong alliances.

2. Preserving Freedom of Navigation

The South China Sea is a vital waterway for global trade, with one-third of the world’s goods passing through its waters. U.S. bases ensure:

Open Access: Preventing any single nation from monopolizing control of the region’s waterways.
Trade Security: Ensuring global trade routes remain open to all nations, regardless of political or territorial disputes.

Without such oversight, China could potentially block access to nations it disputes with, destabilizing global trade. This protection benefits all nations, not just the U.S.

3. Preventing Regional Conflicts

The U.S. presence acts as a deterrent to war between nations in Southeast Asia. If two smaller countries were to engage in conflict:

The U.S. could intervene diplomatically or militarily to de-escalate tensions.
In the absence of U.S. bases, China could exploit such conflicts to expand its influence or impose governance over weakened states.

This role of stabilizing volatile situations mirrors historical patterns where external powers intervened to prevent smaller nations from falling under the control of larger, aggressive neighbours.

4. Ensuring Democratic Decision-Making

U.S. alliances and actions in Southeast Asia are backed by democratically elected governments, ensuring:

Accountability: Security decisions reflect the will of the people in allied nations.
Global Norms: Critical decisions about trade and security are made collectively, not unilaterally by an un-elected power.

This stands in contrast to authoritarian regimes like China, where strategic decisions may prioritize national dominance over global stability.

5. Balancing Power Differentials

The disparity in military and economic power between China and its neighbours necessitates external balancing. U.S. bases provide:

Regional Stability: Ensuring nations like Taiwan and South Korea are not overpowered in disputes.
Peace Through Strength: Reducing the likelihood of conflict by maintaining a balance of power.

This balance is vital for preventing unilateral dominance and ensuring all nations can coexist peacefully.

6. Economic and Security Interests

The U.S. and other democratic nations have made significant investments in Southeast Asia. These investments:

Foster Development: Supporting infrastructure, trade, and technological growth in the region.
Ensure Stability: U.S. bases protect these investments from instability or aggression, safeguarding economic progress.

Moreover, a stable Southeast Asia benefits the global economy, making U.S. involvement in the region a shared interest for many nations.

7. De-escalation and Neutrality

The U.S. presence provides a neutral counterweight in Southeast Asia, ensuring:

De-Escalation Opportunities: Offering a trusted intermediary to prevent or resolve conflicts.
Reduced Regional Tensions: Preventing any single power, including China or the U.S., from unilaterally controlling the region.

This neutrality maximizes opportunities for peaceful resolutions and regional cooperation.

Conclusion: Stability Through Balance

The U.S. bases in Southeast Asia are not an act of aggression but a strategic necessity to maintain regional stability, defend smaller allies, and ensure the free flow of trade. Drawing parallels to Romania’s history, we see that smaller nations often suffer when there is no external balancing force against larger neighbours. U.S. bases provide:

Security for smaller nations.
Economic stability for global trade.
A framework for democratic decision-making.

While containment of adversaries like China is a factor, the broader purpose of these bases is to uphold international norms, prevent regional conflicts, and foster a stable, cooperative environment for all nations. Without these bases, the balance of power would shift dramatically, increasing the risk of domination, conflict, and economic instability.
