US National Security Strategy 2025: Asia and Indo-Pacific in Focus

Sulochana Ramiah Mohan

The 2025 US National Security Strategy (NSS), released in early December, offers one of the clearest articulations yet of the Trump administration’s vision for America’s role in a rapidly shifting global order. Usually, the report is released at the end of the year. The White House says that drafting an NSS is a complex interagency exercise involving the State Department, the Pentagon, the Treasury and the intelligence community, aimed at aligning policy priorities and ensuring political feasibility.

As with previous iterations, the NSS does not offer operational detail. Those specifics belong to the National Defence Strategy, federal budgets and departmental planning documents. Instead, the NSS establishes a strategic framework, defining US priorities, identifying risks and opportunities, and signalling where Washington intends to focus its political, economic and military capital. In this respect, the 2025 document is unambiguous: Asia and the Indo-Pacific sit at the centre of US strategic planning for the coming years.

At its core, the strategy revolves around three fundamental questions: what should the United States seek to achieve, what resources and tools are available, and how can ends and means be linked into a viable national strategy? The answers reflect an approach that is results-orientated, sovereignty-centred and deeply transactional. The NSS firmly situates itself within an “America First” worldview, emphasising national control, economic resilience and the protection of core US interests.

While the document reaffirms the importance of maintaining American influence abroad, it also signals a clear shift away from expansive global leadership towards selective engagement. Rather than attempting to shape outcomes everywhere, Washington intends to concentrate on regions that directly affect US security, prosperity and long-term competitiveness.

The US wants unrivalled soft power
One of the more striking features of the 2025 NSS is its restrained treatment of traditional soft power. Although it acknowledges America’s “unrivalled soft power”, diplomacy, cultural engagement and values promotion are framed primarily as instruments of national advantage rather than intrinsic goals. These tools matter only insofar as they deliver tangible returns for US interests. This transactional logic extends to alliances and multilateral institutions. They are not discarded, but their value is assessed by how closely they align with American priorities. This approach has drawn criticism, particularly in Europe, where some analysts warn that de-emphasising alliances could weaken NATO cohesion and echo narratives favourable to Russia. The NSS, however, reflects a deliberate calculation: partnerships are assets, not obligations.

No single power can dominate Asia
In the Indo-Pacific, the strategy shows far greater continuity with previous administrations. The document reiterates that the United States will not allow any single power to dominate the region, a principle consistent from the Obama administration through the Biden years. Asia is framed both as an arena of strategic competition, particularly with China, and as a region of immense opportunity driven by economic dynamism and technological innovation.

Crucially, the NSS stresses that the regional powers must play a larger role in maintaining stability. This reflects an approach that favours restraint over primacy, aiming to avoid overextension while preserving US influence through selective partnerships. Rather than acting as the sole guarantor of regional order, Washington seeks to shape outcomes by enabling allies and partners to shoulder greater responsibility.

India figures prominently in this vision. The NSS highlights the importance of strengthening commercial and broader relations with New Delhi, explicitly recognising India’s preference for a multipolar world order. Rather than pushing India into a rigid alliance framework, the strategy positions it as a key partner in maintaining regional balance, reflecting a pragmatic appreciation of India’s strategic autonomy.

The Indian interest
The emphasis on preventing any single power from dominating Asia aligns closely with Indian interests and provides clarity on Washington’s perspective regarding China. At the same time, the NSS highlights the importance of increased commerce with Beijing, exposing a central tension in US strategy. If economic engagement with China remains a priority, questions inevitably arise about how far the United States would go in supporting India’s security concerns should economic and strategic interests diverge.

The report gives a detailed treatment of Asia; South Asia is not presented as a standalone strategic theatre. Instead, it is addressed selectively, primarily through India’s role, counterterrorism concerns and the China factor. The NSS signals a move away from earlier US approaches that focused heavily on Afghanistan, Pakistan and regional crisis management, expressing both fatigue from prolonged conflicts and a recalibration of priorities.

India thus emerges as the anchor of US policy in South Asia. Pakistan and Afghanistan receive minimal attention, a clear de-prioritisation.

Counterterrorism remains relevant, but nation-building and long-term military commitments are explicitly avoided, with regional actors expected to take primary responsibility for stability.

More broadly, the NSS embraces a balance-of-power approach. While rejecting the pursuit of global domination, the United States commits to working with allies and partners to prevent any regional or global power from threatening American interests. A pragmatic understanding of contemporary international politics – power is unevenly distributed and stability depends on preventing its excessive concentration – is expressed.

Military and economic considerations are closely intertwined in the Indo-Pacific strategy. The NSS calls on allies and partners to enhance defence spending, capabilities and interoperability. This applies not only to longstanding allies such as Japan and South Korea but also to emerging partners in Southeast Asia. On the economic front, trade, technology cooperation and supply-chain resilience are framed as strategic tools designed to counterbalance China’s influence and ensure that economic integration supports, rather than undermines, security objectives.

The document also addresses Taiwan and maritime security, reaffirming US commitment to freedom of navigation in the South China Sea and stability across the Taiwan Strait. Strategic ambiguity remains central, but the NSS signals that unilateral attempts to alter the status quo would be met with collective deterrence through alliances and forward presence.
