Trump Is Siege-Engineering the ICC — From Inside Its Own Courtroom

The Credit Card That Broke First

Tomoko Arakaki could not pay for her hotel in The Hague. Not because she lacked funds — she had them — but because her credit card no longer worked. A US Treasury designation had severed her from the global payments rails that keep a judge, let alone a court president, functional.

She told this not in a backroom briefing but on a screen addressed to Japanese reporters on August 26th, from the ICC’s own building in The Hague. The setting was deliberate: she was speaking from inside the institution she refused to surrender.

What followed was not outrage but explanation. Arakaki described the mechanics of exclusion — how a single designation cascades through Visa, Mastercard, SWIFT, and correspondent banking relationships. Her card had been rejected at a hotel checkout desk, then again at a restaurant, then again at an ATM. By the third incident, she understood the architecture she had stepped into.

Nine Out of Eighteen

The numbers tell the real story. Of the ICC’s eighteen judges, nine now bear US sanctions. That is not a proportion that invites speculation about isolated retaliation. That is a systematic culling. The court’s bench is effectively half-blocked from the financial systems the United States oversees or heavily influences.

Arakaki herself is a case study in escalation. Japan-trained, former prosecutor, appointed to the ICC in 2018. Russia designated her a wanted person in 2023 after she issued the arrest warrant for Vladimir Putin over war crimes in Ukraine. The US moved against her in August 2026, four years later, as part of a broader campaign to neuter the court.

The sequencing matters: Russia punished her for prosecuting its president. The US punished her for sitting on a court that would do the same to anyone, including American allies or citizens. The target is not a judicial decision. It is the mechanism.

Secondary effects are already visible. Judges without functional bank accounts cannot travel to file documents. They cannot receive honoraria or reimbursements. They cannot meet in The Hague without arranging alternative payment systems — a luxury available only to governments willing to absorb the friction.

The Japanese Pressure Point

What makes Arakaki’s press conference noteworthy is not her defiance — it is her audience. She did not address Brussels or The Hague first. She spoke in Japanese, to the Japan Journalists Club, and directly appealed to Tokyo.

Prime Minister Sanae Takaichi had called the sanctions incompatible with Japan’s position and a serious concern. Arakaki thanked her. Then she pivoted to what Japan could actually do: explain the ICC’s importance to Washington, sustain dialogue, prevent further escalation.

Her argument rested on a claim about Japan’s identity. “Japan has built the rule of law into the pillar of its diplomacy,” she said. “The world’s expectations of Japan are large.” She was asking Japan to act like its own stated principles require — not as a US subordinate but as a state that has, for decades, positioned itself as a rule-of-law advocate in a region defined by legal ambiguity.

That is a tall ask. Japan’s security architecture is US-aligned. Its trade relations are deeply intertwined with Washington. But its foreign ministry has long spoken the language of international law, and Arakaki was essentially offering a moment when that language could mean something concrete.

Japan’s response so far has been calibrated. Foreign Minister Yoko Kamikawa stated that Tokyo “monitors developments with concern” and “urges all parties to respect judicial independence.” No sanctions were imposed on US officials. No payment systems were created to circumvent Treasury designations. The language was precise — concern without action, observation without intervention.

Who Leaves Next?

The withdrawal tide is already moving. Venezuela and Chad have signalled intent to leave this year. The US is actively encouraging member states to follow. Each departure weakens the court’s political legitimacy even as it narrows its jurisdictional reach.

Africa has been the ICC’s most consistent critic — a continent that feels selectively prosecuted. Arakaki is not naive about that. Her request that Japan lobby against withdrawals is an implicit acknowledgment that the court cannot survive on European goodwill alone. It needs members from the Global South who still see it as a necessary check, however imperfect.

If another dozen countries defect, the ICC becomes a regional tribunal with universal ambitions — a far more vulnerable entity than the one that issued the Putin warrant.

Second-order effects are compounding. Legal advisers in member states are already reviewing withdrawal clauses. Embassies are fielding calls from constituents who want to know whether their tax dollars sustain an institution that may not exist in five years. The court’s registry reports declining inquiries from new member applications — a quiet indicator of nervousness among prospective entrants.

The Strategic Logic of Sanctioning a Court

Previous US sanctions against the ICC targeted specific individuals: prosecutors, officials. This campaign is structurally different. Nine of eighteen judges sanctioned is not an attack on a prosecutor’s office. It is an attack on the court’s ability to convene, to rule, to function with anything approaching normalcy.

The credit card detail is symbolic but not trivial. Judicial independence is not sustained by declarations. It is sustained by the mundane infrastructure of movement, payment, communication. When you cut those, you do not need to close the court’s doors. The doors close themselves.

This is not the first time the US has confronted the ICC. Trump’s 2020 sanctions on ICC prosecutor Fatou Bensouda and others were notable. Those targeted individuals. This targets structure.

The escalation follows a logic: punish the court’s head, then its body, then its capacity to operate. Each step narrows the field of possibility without triggering a direct military or diplomatic confrontation. The ICC cannot retaliate. It has no enforcement mechanism beyond moral authority — and moral authority proves brittle when presidents refuse to appear.

What Happens Next Depends on Two Things

First, whether Japan and a handful of other middle powers treat Arakaki’s appeal as a genuine inflection point or as a diplomatic inconvenience to be acknowledged and deflected. Second, whether the remaining nine judges can continue working while half their colleagues are financially isolated — a question that has no clean answer.

Arakaki said the ICC would never lose. That is the language of conviction, not calculation. What remains to be seen is whether the institution’s supporters will match that language with action, or merely with statements like Takaichi’s — serious concern, incompatible with our position, full stop.

The credit card was the first domino. The question is what topples next.
