最具体的压力点是市场准入与监管。德国和欧盟经济学家估计，欧盟单一市场拥有 4.5 亿高收入消费者，对依赖美国企业有显著杠杆，尤其是与 Donald Trump 和 JD Vance 关系密切的公司；在既有数字立法下，对 Alphabet、Amazon 或 Meta 征收新税、罚款或设置运营限制可削弱其利润。官员还确认 AI 供应链压力：OpenAI、Anthropic、Microsoft 各单位与 Elon Musk 的 X 在数据中心扩张中部分依赖欧洲工业投入，包括 Siemens 的专用设备。半导体依赖性更具后果：美国芯片生产仍依赖欧洲化学品，以及 ASML 及德国供应商 Zeiss、Trumpf 提供的先进光刻设备；与此同时，欧盟通过工业加速法案等政策提高本土企业在公共采购中的优先度并推动更多欧洲部件应用，旨在支撑制造基础并对冲美国与中国竞争。
其他数据既揭示机会，也显示威慑限制。欧洲供应了美国所有品牌药物活性成分几乎一半，以及 90% 的胰岛素；泛欧工商会议会指出，在全球供应链细分中，近 300 个类别对欧洲依赖度为 100%，超过 700 个类别则达到 90% 及以上。尽管如此，政策制定者也把报复风险视为严重：欧洲持有美国 10.4 万亿美元股票（约占市值的 15.3%）、34,000 亿美元美国国债和 2.9 万亿美元美国企业债。德国和欧洲官员指出，由于美国市场和美元的主导地位，大规模资产抛售会给欧洲带来显著连带伤害。安全上的相互依存亦是硬约束：泛欧工商会议会估算，如美国失去欧洲基地的全球投送能力，若无 NATO 补位，替代成本每年将达 100 亿至 2000 亿美元，因此柏林在施压时必须权衡该依赖与乌克兰战争下欧洲安全现实。
German officials are building a coordinated plan for if the next U.S.-Europe confrontation occurs. Berlin has started mapping U.S. supply-chain vulnerabilities and EU leverage points, aiming to align partners on possible countermeasures during a future dispute with the White House. The initiative, partly triggered by Trump’s hardline stance and the earlier Greenland proposal, is intended to strengthen collective bargaining rather than escalate conflict; officials say its preferred outcome is a repaired transatlantic relationship. Economists and officials say Europe also wants to defend interests in Trump-linked sectors, AI investment channels, and sensitive consumer issues such as drug prices, but no final decision to activate coercive measures has been made.
The most concrete pressure points are market access and regulation. German and EU economists estimate that the EU single market’s 450 million affluent consumers gives major leverage, especially over U.S. firms with close ties to Donald Trump and JD Vance; under existing digital laws, new taxes, fines, or operational restrictions on Alphabet, Amazon, or Meta could reduce their profits. Officials also identified AI-supply-chain pressure: OpenAI, Anthropic, Microsoft units, and Elon Musk’s X depend in part on European industrial inputs, including specialized equipment from Siemens, for data-center expansion. Semiconductor dependence has even greater consequences: U.S. chip production still depends on European chemicals and advanced lithography from ASML and German suppliers Zeiss and Trumpf; at the same time, EU industrial policies such as the Industrial Acceleration Act raise local firms in public procurement and push greater use of European components.

Other data reveal both opportunity and limits to deterrence. Europe supplies nearly half of active ingredients for U.S. branded medicines and 90% of U.S. insulin, and the chamber cited almost 300 categories in global supply chains with 100% European dependence and over 700 categories at 90% or above. Policymakers nevertheless treat retaliation risk as severe: Europe holds $10.4 trillion in U.S. equities (about 15.3% of market value), $3.4 trillion in U.S. Treasuries, and $2.9 trillion in U.S. corporate bonds, and experts say large-scale asset sales could cause major collateral damage to Europe under U.S. market and dollar dominance. Another hard constraint is security interdependence: the chamber estimates replacing Europe’s U.S. military-basing role outside NATO would cost the U.S. $100-$200 billion annually, so Berlin must weigh coercive options against the dependence on U.S. security and the realities of the Ukraine war.
