The ongoing conflict in the Middle East is exposing critical shifts in global energy dynamics and challenging the cohesion of the North Atlantic Treaty Organization (NATO), with significant implications for Europe and Western security.
Historically the dominant player in ensuring stability and the flow of global public goods, particularly in energy, the United States now finds its traditional role increasingly questioned. Unlike the United Kingdom and the European Union, both heavily reliant on energy imports—with the EU importing about 57% of its needs and the UK around 44%—the US has become a net energy exporter. This shift has enabled the American economy to better withstand disruptions caused by the conflict. According to assessments by the Organisation for Economic Co-operation and Development (OECD), the war is projected to reduce UK and eurozone economic growth by approximately 0.4 to 0.5 percentage points, while US growth is expected to increase slightly by 0.3 percentage points.
The recalibration of energy independence in the US raises concerns about the degree to which Washington will continue to safeguard global energy routes such as the Strait of Hormuz. During recent hostilities, the US proved unable to maintain uninterrupted access to this critical chokepoint and has struggled to restore previous conditions fully. There is growing speculation that an energy self-sufficient America may reduce its commitments abroad, effectively shifting the burden of securing energy flows to other nations. Former US President Donald Trump has frequently suggested that the responsibility for keeping such routes open lies with other countries rather than the United States.
Meanwhile, the prospect of increased Chinese influence in global energy markets adds further complexity. Beijing is expected to leverage energy as a strategic tool, mirroring its broader approach to global power projection, which complicates efforts by Western nations to maintain energy security without increased diversification and domestic investment. This underscores calls for greater development of resources such as North Sea oil, nuclear energy, and improved energy storage technologies in Europe to bolster resilience.
The war has also underlined NATO's vulnerabilities and tested alliance solidarity. Although Washington had previously criticized member states for insufficient defense spending, many allies have responded by increasing their defense budgets—in 2025, NATO countries collectively are set to spend about 20% more on defense than the previous year. Despite this upward trend, concerns persist regarding the United Kingdom’s hesitance to fully fund its strategic defense commitments, risking diminished influence within the alliance at a time when Western security frameworks are rapidly evolving.
Tensions within NATO continue as well, with friction anticipated over US military bases and strategic locations, such as Greenland. Disputes over sovereignty and base access risk further straining alliance cohesion at a moment when unity is crucial, especially given the ongoing war on NATO’s eastern frontier.
The conflict’s broader impact reverberates in Ukraine, which has gained new defense partnerships with countries in the Gulf region but remains under pressure from Washington to concede territory as part of diplomatic efforts to end wars it is entangled in indirectly. This dynamic reflects Europe’s continued security dependency on the US, despite the challenges posed by changing American priorities in the Middle East and beyond.
As energy independence reshapes US foreign policy and NATO grapples with internal divisions, the global order faces uncertainty. The evolving landscape raises pressing questions about the future roles of America, Europe, and emerging powers in maintaining international stability amid ongoing geopolitical turbulence.
