On June 25, 2025, at the NATO summit in The Hague, leaders of the alliance’s 32 member countries agreed to increase defense spending to 5% of GDP by 2035. This decision was the result of prolonged pressure from U.S. President Donald Trump, who repeatedly criticized European allies for insufficient defense spending. However, behind the scenes of this process was powerful lobbying activity that played a key role in achieving this goal.
According to AP News, Trump repeatedly expressed dissatisfaction with the low level of defense spending among European NATO countries, which he believed threatened the security of the alliance and unfairly burdened the United States. He even threatened to reconsider the U.S. participation in NATO if the allies did not increase their contributions. This pressure forced European leaders to reconsider their positions and agree to increase spending.
However, experts say that such changes would not have occurred without active lobbying efforts. Powerful defense corporations and associations, especially from the U.S., actively influenced politicians and governments of NATO countries, promoting the interests of their companies. These lobbyists organized meetings with high-ranking officials, provided financial support to political campaigns, and influenced defense policy formation through think tanks and the media.
In particular, ahead of the summit in The Hague, NATO leaders, including Secretary General Mark Rutte, actively collaborated with lobbyists to develop a strategy that would meet Trump’s demands while remaining acceptable to European countries. This resulted in a compromise: 3.5% of GDP on core defense needs and 1.5% on additional security measures such as cybersecurity and infrastructure.
This case vividly demonstrates how lobbying can influence international decisions and shift the balance of power in global politics. Although decisions are officially made by state leaders, behind the scenes there are often powerful economic interests shaping the future of international relations.
