When Russia invaded Ukraine in 2022, energy quickly became a geopolitical weapon. Moscow curtailed natural gas flows to Europe, exploiting the continent’s heavy reliance on Russian supply. The disruption sent prices sharply higher and exposed the fragility of Europe’s energy model. Liquefied natural gas shipments, particularly from the United States, helped stabilize markets and replace lost volumes. At the time, the shift was widely viewed as a strategic success.
Three years later, that solution is drawing renewed scrutiny. Europe has traded one dominant supplier for another, and analysts increasingly view the resulting dependency as a potential pressure point rather than a safeguard. U.S. LNG has moved from a marginal role to a central one in Europe’s energy system, accounting for more than a quarter of European Union gas imports in 2025, up from roughly 5 percent in 2019.
Before the war, Russian gas supplied more than half of the European Union’s imports. That flow collapsed after the invasion as pipeline deliveries through Ukraine and Poland, as well as under the Baltic Sea, fell sharply. The resulting supply shock strained households, industrial producers, and government budgets across the continent. American LNG shipments, delivered to ports in countries including the Netherlands, France, and Belgium, filled much of the gap and helped contain price volatility.
The political context has since shifted. President Donald Trump, now in his second term, has shown a willingness to use trade relationships as leverage in broader disputes with allies, including recent tensions involving Greenland. European policymakers and analysts are increasingly concerned that Washington could apply similar pressure through energy exports, turning the United States’ dominant position in LNG into a bargaining tool.
That concern is reinforced by policy choices on both sides of the Atlantic. The Trump administration actively encouraged Europe to increase purchases of U.S. LNG as part of a trade agreement concluded last year. As a result, American LNG deliveries to the European Union rose by roughly 60 percent in 2025 alone. At the same time, Europe has accelerated efforts to reduce residual Russian imports, which fell to around 12 percent of total gas imports last year.
Europe’s options remain limited. Natural gas is still essential for heating, electricity generation during renewable shortfalls, and industrial processes. Domestic production is declining as mature fields wind down, and several countries discourage new drilling. Norway, now Europe’s largest supplier, provides about 30 percent of imports, but spare capacity is finite. Analysts broadly agree that meaningful substitution away from gas will take years, not months.
The structure of the U.S. gas industry does reduce the risk of outright supply cuts. Unlike Russia’s state-controlled exporter Gazprom, U.S. LNG exports are produced and shipped by private firms responding to market incentives. Companies such as Cheniere Energy have invested heavily in export terminals along the Gulf Coast, with Europe a natural destination given shorter shipping distances and weaker Chinese demand. Abrupt political interference would undermine those investments and damage U.S. credibility as a supplier.
Still, analysts warn that even modest policy actions, such as export taxes or regulatory delays, could raise costs and introduce uncertainty. Europe’s growing import concentration around U.S. LNG increases its exposure to disruptions centered outside the continent. The shift away from Russian gas reduced one form of vulnerability, but it did not eliminate Europe’s underlying dependence on external energy suppliers. It merely changed the source.
