New National Security Strategy from Trump Administration
Recently, the Trump administration issued a statement regarding its national security strategy. It emphasized that the era of the U.S. providing extensive support across the global order is coming to an end. The administration noted that allies should take more initiative in ensuring the security of their regions. This shift is particularly directed at Europe as the U.S. turns its focus towards the Western Hemisphere and enhances military presence in the Western Pacific.
The strategy document highlighted the need for “Europe to stand on its own two feet,” urging it to operate as a collective of independent states responsible for its own defense.
However, there seems to be a strong desire among lawmakers for the U.S. to continue its role in defending Europe for the foreseeable future.
To reduce the number of U.S. troops below the current 76,000 stationed in Europe, the Trump administration would have to demonstrate to Congress that such a decision would not threaten U.S. or NATO security interests.
The latest iteration of the 2026 National Defense Authorization Act (NDAA), which was finalized by House and Senate negotiators and released recently, proposes a budget of $8 billion over President Trump’s request of $892.6 billion for the Pentagon. The bill restricts troop withdrawals from the U.S. European Command Area of Responsibility for more than 45 days, ensuring the number doesn’t fall below 76,000. It also prevents using allocated funds to relocate Defense Department equipment outside Europe, which is initially valued at $500,000.
The number of U.S. troops in Europe typically varies between 80,000 and 100,000.
Reports from Reuters, citing five sources familiar with discussions, revealed that Pentagon officials recently informed European diplomats that by 2027, the U.S. expects Europe to manage most of NATO’s conventional defense capabilities, including military and missile defense. If this expectation goes unmet, the U.S. might reconsider its involvement in certain NATO defense coordination roles.
Pentagon spokesperson Kingsley Wilson stated, “We clearly express the need for European leadership in conventional defense.” He added that, as European allies take on more responsibility for defense, the U.S. is committed to strengthening NATO’s coordination mechanisms to ensure their longevity.
In addition, Christopher Landau, the Deputy Secretary of State, emphasized that “Europe must take primary responsibility for its own security,” pointing out that this is a longstanding sentiment echoed by various U.S. administrations, including the Nixon Doctrine. However, he suggested that the current administration genuinely means it.
The NDAA also contains provisions that would ensure the Air Force Gen. Alexis Grinkevitch, head of U.S. European Command, continues in his role as supreme allied commander of NATO forces in Europe. Meanwhile, Democrats, like Senator Dick Durbin from Illinois, have pushed to codify the Baltic Security Initiative, which provides U.S. funding for the defense forces of Baltic states. This initiative has received significant investment over recent years, even as these countries increase their own defense spending.
The bill also includes elements that might impede the administration’s attempts to fully implement its national security strategy. It expresses a sense of Congress urging the Secretary of Defense to strengthen defense alliances in the Indo-Pacific region to enhance U.S. advantages amid the strategic competition with China. The bill also prevents any changes that might drop troop strength in South Korea below 28,500 or transition the combined wartime command to a South Korean-led command, without proper assessments submitted to Congress.
