ICC's Kress tells Nikkei Asia that court can withstand US sanctions, if its supporters hold

Claus Kress, special adviser on the crime of aggression to the Office of the Prosecutor of the International Criminal Court, told Nikkei Asia on 10 October 2026 that attempts to destroy the court will fail if its core supporters remain steadfast, and called on major countries, including Japan, to stand together, according to the outlet's reporting that day.

The intervention matters because it puts a senior legal figure inside the prosecutor's office on the record in a commercial-Asian outlet with global readership, rather than in the institutional press releases that the court usually relies on for public messaging. Kress's framing is conditional rather than declarative: the court holds, he argues, only if state parties hold with it. That conditional matters, because it converts a question of institutional independence into a question of coalition discipline.

What Kress is signalling

Kress's decision to comment is itself a signal. Special advisers to the Office of the Prosecutor rarely address geopolitical disputes in commercial media; their work is technical, and the court's communications team usually speaks for the institution. By choosing to address sanctions as a structural threat, and by naming Japan among the countries whose unity he is asking for, Kress is indicating that the Office reads the present moment as one requiring legal authority, not press-release diplomacy.

The substance of the comment, as reported by Nikkei Asia, is a conditional rather than a promise. Kress's argument, in the outlet's paraphrase, is that attempts to destroy the court will fail if core supporters remain steadfast. The available source items do not specify which additional officials Kress named, which other state parties he referenced, or which prosecutorial decisions he previewed. Monexus analysis: the conditional formulation reads as a deliberate choice, because it puts the cost of any future failure on the coalition, not on the Office of the Prosecutor.

The sanctions regime as reported

The available source items do not specify the full text of the latest US measures against the court, nor do they enumerate which specific tools (visa restrictions, asset freezes, secondary sanctions, or other mechanisms) appear in the most recent round. The United States is not a state party to the Rome Statute, and the available source items do not specify which extraterritorial levers Washington is currently using against the court or its officials.

What the source items do establish is that Kress, in his Nikkei Asia remarks, treats the pressure as an attempt to destroy the court rather than a routine policy disagreement, and that he frames resistance as a question of whether core supporters remain steadfast. The available source items do not specify the operational impact of the measures on court staff, the number of officials sanctioned to date, or the financial effect on the court's assessed contributions. Monexus analysis: in the absence of specifics on the sanctions tools, the public fight is being conducted in the court of coalition politics rather than in the court of compliance.

The counter-reading

The dominant Western wire line treats the ICC as a judicial body under duress and frames Kress's remarks as a morale-and-resourcing intervention. The counter-reading, common in Global-South legal commentary and among states that have themselves experienced ICC jurisdiction, treats the standoff as a moment of multilateral fracture: when a major power withdraws cooperation, the court's perceived legitimacy in post-colonial contexts becomes harder to defend against governments that already view the court as selective. In that reading, Kress's conditional is necessary precisely because the legitimacy question is unresolved among the court's own constituency, and because appeals to unity will not by themselves repair that perception.

The available source items do not specify which state parties have publicly questioned recent ICC activity, nor do they enumerate African Union positions on the court, nor do they record which major countries besides Japan have been singled out in Kress's appeal. Monexus analysis: the court can hold its line procedurally while losing ground politically, and Kress's conditional reads as an attempt to stabilise the procedural front without resolving the political one.

What to watch next

The near-term test is cooperation on active warrants. If a state party arrests a sanctioned official for transfer to The Hague in the coming months, the sanctions regime will have failed at its most basic level. If no transfer occurs and the court's docket visibly slows, the regime has succeeded at eroding the cooperation network without forcing a withdrawal. The longer test is whether state parties move to insulate the court from secondary pressure, and whether Japan's response, named explicitly in Kress's remarks, translates into concrete diplomatic cover.

The available source items do not specify whether any Tokyo official has responded on the record to Kress's appeal, nor whether the court's Trust Fund for affected staff has received new pledges since the most recent sanctions were announced. The next ICC budget session will show whether financial insulation holds; the next filing cycle will show whether Kress's conditional has been underwritten by member states, or only by the prosecutor's office.

How Monexus framed this: the wire services reported Kress's remarks as a quote-driven morale statement; we read them as a conditional strategic legal intervention that places the burden of continuity on the court's core supporters, including Japan, and we surface the Global-South counter-reading alongside the dominant institutional frame while flagging which claims the available source items do not specify.
