Trump threatened 100% tariffs on Europe. Here’s why nobody flinched

Trump’s Tariff Threat Against Europe: Why the Global Response Has Stayed Calm

Trump threatened 100 tariffs on Europe – President Donald Trump’s latest tariff warning has stirred little reaction from international partners, a stark contrast to the frenzy he once provoked a year ago. In 2025, his aggressive stance on levies sent shockwaves through global markets and prompted urgent diplomatic efforts. Today, even as he threatens to impose 100% tariffs on European imports, the response is muted. This shift in perception is largely due to a February Supreme Court decision that significantly curtailed his ability to act unilaterally on trade matters. While the ruling hasn’t stopped Trump from making bold declarations, it has forced him into a more measured approach.

Supreme Court Limits Presidential Power Over Tariffs

The landmark ruling in February reshaped the landscape of U.S. trade policy by stripping Trump of his most flexible tool for imposing tariffs. The court determined that the president’s authority under the International Emergency Economic Powers Act (IEEPA) was insufficient to justify sudden, sweeping levies on goods from allies. This decision came after years of legal battles over the scope of presidential power in trade, with critics arguing that the law had been stretched to its limits. The ruling underscored the need for Congress to clearly define its delegations, a principle emphasized by Chief Justice John Roberts in his majority opinion.

“When Congress grants the power to impose tariffs, it does so clearly and with careful constraints,” Roberts wrote. “It did neither here.”

Jeffrey Schwab, senior counsel at the Liberty Justice Center, which spearheaded the case against the IEEPA’s use, elaborated on the implications. “The president cannot impose tariffs without following specific procedures and meeting defined conditions,” Schwab explained to CNN on Friday. This means Trump’s past threats, such as the 2025 tariff announcements, now require more formal processes. The legal framework, while still allowing for trade actions, demands greater transparency and adherence to statutory guidelines, limiting the speed at which tariffs can be implemented.

Trump’s New Threat: A 100% Tariff on Europe

Despite these constraints, Trump continues to wield his tariff rhetoric as a strategic tool. On Friday, he posted on Truth Social, declaring that any European nation adopting a digital services tax would face “immediate 100% tariffs” on all goods shipped to the U.S. This new threat is not just a bluff; it’s a calculated move to pressure allies into concessions. The digital services tax, a levy on tech companies operating online, has become a focal point in trade disputes. By targeting this tax, Trump aims to highlight perceived unfairness toward American firms, which dominate the digital services sector.

Such taxes are designed to extract revenue from large multinational corporations, even those that operate at a loss. European countries have introduced these taxes to address the growing influence of tech giants like Google and Spotify, which generate vast profits but pay minimal taxes in their home countries. Trump has long argued that these measures unfairly burden American companies, and the Congressional Research Service, a nonpartisan agency, echoed this sentiment in some cases. However, the recent Supreme Court ruling complicates his ability to enforce such threats directly.

The Legal Roadblock: A Year of Controversy

Previously, Trump had relied on the IEEPA to impose tariffs, a 1974 law that grants the president broad authority to regulate economic activity during emergencies. This tool allowed him to bypass congressional approval and act swiftly, which he used to great effect in 2025. However, the court ruled that this approach exceeded his constitutional powers, citing the lack of clear parameters in the law. The decision marked a turning point, as it established that the president must now justify tariffs with more specific evidence and procedures.

“None of the authority Congress has granted the president to impose tariffs allows him to do so whenever he wants,” Schwab noted, highlighting the bureaucratic hurdles now in place. While Trump can still initiate investigations and propose tariffs, the process now requires collaboration with the Treasury Department and formal approval from trade officials. This has forced him to adopt a more deliberate strategy, even as he maintains his aggressive tone.

Plan B: A Uniform 10% Tariff and Section 301 Investigations

Following the February ruling, the administration shifted to a more structured approach. Instead of sudden 100% levies, they proposed a uniform 10% tariff, which is set to expire next month. This temporary measure allows for flexibility while giving the administration time to build a stronger case for more permanent changes. Alongside this, Trump has revived Section 301 investigations, a trade law used to challenge unfair practices by foreign nations. These investigations could lead to higher tariffs, but they typically take months to resolve, as the U.S. Trade Representative must gather evidence and negotiate with the targeted country.

During his first term, Trump initiated multiple Section 301 probes into European digital services taxes, though they resulted in limited action. The investigations were used more as diplomatic leverage than as a means to immediately raise tariffs. Now, with the same tools available, there is speculation that Trump may fast-track the process this time. However, the constraints imposed by the Supreme Court mean that even the most aggressive threats face significant legal scrutiny.

Analysts suggest that Trump’s 100% tariff threat, while attention-grabbing, is unlikely to materialize without a formal justification. The shift from direct threats to a more procedural approach reflects the administration’s adaptation to the new legal landscape. While the president remains a vocal advocate for protectionist policies, his ability to act unilaterally has been constrained, leaving him to rely on a combination of legal tools and political pressure.

A New Era for U.S.-Europe Trade Relations

The current situation signals a new phase in U.S.-Europe trade dynamics. With the Supreme Court’s ruling, Trump’s former playbook of shock and awe is less effective, and his threats must now align with legislative frameworks. This has forced him to engage in a more nuanced dialogue, even as he continues to emphasize the need for American interests to be protected. The digital services tax remains a central issue, and while Trump’s threat is a reminder of his trade ambitions, the reality is that his options are now more limited.

As the administration moves forward, the balance between presidential authority and congressional oversight will be critical. The ruling has set a precedent that future trade actions must follow, ensuring that the U.S. government cannot act in isolation without clear mandates. For now, Trump’s 100% tariff warning stands as a symbolic gesture, rather than a concrete policy. The global market, having grown accustomed to his previous tactics, remains largely unfazed, waiting to see if his new approach will lead to real change or simply another round of rhetoric.
