What happened?
On 05 December, the US released National Security Strategy 2025, outlining President Trump's vision of "flexible realism." The strategy places the Western Hemisphere at the core of US foreign policy priorities, describing the shift as a "'Trump Corollary' to the Monroe Doctrine."

The 29-page document states that the US will "restore American preeminence" in the region and strengthen its military posture in the Indo-Pacific. The strategy reflects a reduced emphasis on countering China and Russia and a firm stance toward Europe. It also signals a shift away from democracy promotion and long-standing military entanglements, prioritising economic advantage, regional influence and burden redistribution instead.

The following are the five major takeaways of the report.

1. A Western Hemisphere-First Strategy: Reasserting the Monroe Doctrine
The NSS places the Western Hemisphere at the centre of US foreign policy. Describing this shift as the "'Trump Corollary' to the Monroe Doctrine," the document states that the US will "restore American preeminence" in the region and protect access to key geographies. The NSS directs American embassies to identify "major business opportunities… especially major government contracts," emphasising economic advantage as a central pillar of regional engagement. According to the document: "The terms of our agreements, especially with those countries that depend on us most and therefore over which we have the most leverage, must be sole-source contracts for our companies." The document does not fully clarify deliberations around potential action in Venezuela. However, it notes that America would prioritise working with "regional champions" capable of maintaining stability beyond their borders. It identifies that such partners can help curb illegal migration, neutralize cartels, support nearshoring of manufacturing, and strengthen local private-sector growth. The US is said to incentivise and support governments, political parties, and movements that align with its strategic objectives. Overall, the Western Hemisphere is presented not only as a security priority but as the principal space through which the administration intends to implement its broader economic and geopolitical objectives.

2. A sharper critique of Europe, but a softer approach toward Russia
The National Security Strategy adopts a critical tone toward Europe, stating that the continent is undermining democracy, challenging peace efforts in Ukraine, and facing "civilisational erasure." According to the document, the US views the following as Europe's major challenges: activities of EU and other transnational institutions that weaken sovereignty; migration policies; restrictions on free speech and political opposition, declining birth rates, and an overall erosion of national identity and "self-confidence," which it says is explicit in its approach to Russia. The pointed criticism directed at Europe contrasts with its approach to conventional rivals such as Russia. The NSS recasts America as an arbiter between Europe and Russia, rather than Europe's ally. It notes that a peace deal should both "re-establish strategic stability with Russia" and ensure Ukraine's "survival as a viable state." The document also calls for ending NATO's "perpetually expanding alliance," reinforcing the shift toward a narrower defence role in Europe.

3. China as a primary economic competitor and less of a systemic threat
The NSS downplays countering China, portraying it largely as a commercial competitor rather than a larger threat. It lays out plans to recalibrate the economic relationship, stating: "Going forward, we will rebalance America's economic relationship with China, prioritizing reciprocity and fairness to restore American economic independence."

The strategy positions the US goal of growing from a USD 30 trillion to a USD 40 trillion economy in the 2030s as a key driver of its approach to China. Conflict over Taiwan is also framed mainly in commercial terms: "Given that one-third of global shipping passes annually through the South China Sea, this has major implications for the U.S. economy." It emphasises deterrence through "military overmatch." The NSS calls for a "genuinely mutually advantageous economic relationship" and emphasises stability over escalation in the Indo-Pacific.

4. The Middle East as "a source and destination of international investment"
Departing from long-standing US policy, the document does not present promoting democracy as a key objective. It notes that the traditional drivers of US engagement in the Middle East are expected to diminish. Instead, the Middle East is characterised as "a source and destination of international investment." It says achieving this, however, requires moving away from "America's misguided experiment with hectoring these nations….. especially the Gulf monarchies..into abandoning their traditions and historic forms of government." Reflecting a significant shift in its approach, the NSS notes that the US should support reforms wherever they occur organically in the region rather than impose them. The region is thus reframed as a partner in investment and technology rather than a site of US military engagement or democratic engineering.

5. Africa: shift from an aid-driven approach to one centred on trade, investment and resource access
The document outlines a major shift in US policy from an aid-driven approach to one centred on trade, investment, and resource access. It states: "For far too long, American policy in Africa has focused on providing, and later on spreading, liberal ideology. The United States should instead… transition from a foreign aid paradigm to an investment and growth paradigm." It identifies energy and critical minerals as immediate opportunities for investment and emphasises partnerships with "capable, reliable states" willing to open markets to US goods and services. The NSS also notes the need to monitor "Islamist terrorist activity" while avoiding long-term military commitments. It also partly frames Africa through the lens of resource competition with China, stating that US-backed technologies, including nuclear and LNG, can both support African development and advance US interests.
