US Secretary of State Marco Rubio and NATO Secretary General Mark Rutte on Thursday, 22 May called for urgent expansion of alliance defence production and the protection of freedom of navigation in the Strait of Hormuz, following talks on the sidelines of the NATO Foreign Ministers' Meeting in Helsingborg, Sweden. The bilateral meeting addressed defence spending, military production capacity, Iran's nuclear and missile programmes, and maritime security ahead of the alliance summit scheduled in Ankara later this year.

Key Developments from Helsingborg

According to a State Department readout attributed to spokesperson Tommy Pigott, Rubio and Rutte discussed 'strategic imperatives for the Alliance, including increased Allied defence spending, the upcoming NATO Summit in Ankara, and expanded Transatlantic defence production.' The readout also flagged US opposition to 'protectionist measures that risk NATO interoperability and readiness, weaken the Transatlantic defence industrial base, and jeopardise the ability to deliver equipment to our warfighters.'

Industrial Base Under Strain

Rutte acknowledged that defence budgets across NATO member states are rising sharply. 'The good news is the money is now coming in,' he said. 'Defence spending is rapidly ramping up.' However, he cautioned that the alliance's defence industrial base is struggling to keep pace with demand. 'This is a problem in Europe, this is a problem in the US,' Rutte said, adding that the issue would be 'a big issue at the Ankara Summit.'

Rubio echoed the concern, warning that current munitions output falls well short of future requirements. 'It is clear to the world, to all of us in the Alliance and beyond, that we simply are not able to produce munitions today at a rate that are necessary for future needs,' he said. He described the upcoming Ankara summit as 'probably one of the more important leaders' summit in the history of NATO.'

Hormuz Tensions and Iran's Military Posture

The Strait of Hormuz — through which roughly 20% of global oil supplies transit — emerged as a central security concern. Rutte said NATO ministers were 'deeply concerned' about threats to navigation in the waterway. 'I hear from many of my colleagues here that it's not acceptable that freedom of navigation is basically trampled upon as it is at the moment,' he said.

Rutte also praised recent US military actions, stating that 'the US degrading the nuclear capability of Iran but also the long-range missile capability of Iran, is crucial for the Middle East, for Europe, for the whole world.' Rubio accused Iran of attempting to impose a 'tolling system' in the Strait of Hormuz, calling it flatly 'not acceptable.' He confirmed the US is backing a Bahrain-supported resolution at the United Nations Security Council to safeguard freedom of navigation in international waters, and reiterated Washington's position that 'Iran can never have a nuclear weapon.'

Intra-Alliance Tensions Surface

Rubio did not shy away from acknowledging divisions within the alliance over recent US military operations in the Middle East. 'The President's views — frankly, disappointment — at some of our NATO Allies and their response to our operations in the Middle East, they are well documented,' he said. This comes amid broader transatlantic friction over burden-sharing, trade, and the pace of European rearmament — fault lines that the Ankara summit will be under pressure to paper over.

What Comes Next

All eyes now turn to the NATO Summit in Ankara, where defence industrial capacity and Iran-linked maritime security are set to dominate the agenda. Whether member states can align on concrete production targets — and resolve the US-Europe friction over protectionist procurement — will determine whether the Helsingborg signals translate into binding commitments.
