U.S. Defense Secretary Pete Hegseth called for a "NATO 3.0" reboot during a meeting of defense ministers in Brussels on Thursday [1, 2].

The proposal signals a significant shift in American foreign policy by demanding that European nations assume primary responsibility for their own regional security. This move could alter the long-standing balance of military contributions and presence within the alliance.

Hegseth said the goal is to restore the organization to a stronger, more focused military alliance [1]. He proposed a comprehensive review of U.S. forces currently stationed in Europe to ensure the alliance remains robust and concentrated on its core mission [2].

During the summit, Hegseth said the current structure of the alliance requires an update to meet modern challenges. He said, "We need to reboot NATO into a 'NATO 3.0' that is a stronger, more focused military alliance" [1].

The Defense Secretary also said the necessity of shifting the burden of continental defense. He said, "America's allies in Europe must take the lead on the defense of their own continent and help turn NATO into a hard‑line military alliance" [2].

Dutch Prime Minister Mark Rutte was also mentioned during the discussions regarding the new direction of the alliance [3]. The proposal for NATO 3.0 focuses on streamlining military operations, and ensuring that the U.S. role is supportive rather than primary in European territorial defense [1, 2].

We need to reboot NATO into a 'NATO 3.0' that is a stronger, more focused military alliance.

The push for NATO 3.0 represents a strategic effort by the U.S. to reduce its financial and military overhead in Europe. By framing the reboot as a way to make the alliance 'hard-line' and 'focused,' the U.S. is pressuring European members to increase their own defense spending and capabilities, potentially reducing the U.S. footprint on the continent.
