Trump Pressures NATO Allies on Burden-Sharing as Troop

President Donald Trump has accused NATO allies of being unwilling to join the war in Iran, a conflict he and Israeli Prime Minister Benjamin Netanyahu started without consultations. The administration's campaign for increased burden-sharing appears to be working, with allies increasing defense investments, buying US-made weapons, and bolstering domestic industries.

Allies provided substantive responses to a US questionnaire assessing strategic contributions and loyalty to the president’s policies. The United States is now reviewing troop levels in Europe while ensuring allies step up before any reductions to avoid security risks.

Pentagon's European force posture review

The Pentagon is conducting a six-month review of US troop levels in Europe, launched in late July. This review aims to transition NATO to a new configuration, referred to as NATO 3.0. In this vision, Europe is meant to assume responsibility for conventional defense of the continent while the United States provides critical but more limited support.

Lawmakers used the Pentagon’s annual policy bill to restrict the administration’s ability to cut the US presence in Europe. The bill requires minimum troop levels of 76,000. Any reduction below that threshold would require extensive consultations with allies and Congress, along with steps to mitigate security risks. Approximately eighty thousand US forces are currently deployed in Europe.

Allied responses and defense investments

European allies have responded constructively to US outreach through conversations with officials. Under the NATO 3.0 vision, Europe maintains its own non-nuclear defence. To meet these requirements, European allies have pledged to spend 5 percent of their GDP annually on defense by 2035.

Alliance trust and strategic shifts

Trust within the alliance is fracturing. Some NATO countries have exceptionally low trust in Washington. Some allies are preparing to ride out current turbulence, hoping for change with the next administration. Others believe the damage to trust is more profound.

Signs exist of nations seeking to reduce dependence on US defense technology and industry. In response, some allies placed limits on the US military’s use of their bases and airspace. Europeans have expressed concerns that the US could withdraw troops and equipment before allies are ready to replace them, creating new vulnerabilities.

The Pentagon's top policy official, Under Secretary of Defence for Policy Elbridge Colby, spoke to the Senate Armed Services Committee. His statement was released on September 28 but dated September 22. The Defence Department submitted a 16-page document to committee members after Colby delivered a required briefing on the administration’s 2026 National Defence Strategy. That briefing drew bipartisan criticism for its lack of transparency.

President Donald Trump has signalled his intention to punish allies for perceived disloyalty. Donald Trump, who has long sought to restore American strength and reassert his nation’s leadership role in global affairs, continues to shape the debate. The expectation is clear: allies must demonstrate sufficient replacement capabilities before any US troop reductions can occur.
