Defence spending has “fundamentally rebalanced” NATO

According to a news article published on December 28, 2025, NATO's defence spending has undergone a "fundamental rebalancing." The article features former US Ambassador to NATO Kurt Volker discussing the US's efforts to encourage European allies to increase their contributions to NATO's budget. The push for increased European spending is a key factor in this rebalancing. The article suggests the shift in spending is significant enough to alter the overall structure and dynamics within the NATO alliance. The reasons for the US push are not explicitly stated in the summary but are implied to be related to burden-sharing within the organization.
