Recent data shows that American public trust in the effectiveness of NATO's mutual defense agreements is decreasing.

最近的數據顯示，美國公眾對北約共同防禦協議有效性的信任度正在下降。

A survey of over 31,000 people shows that only 43% of US adults believe that other NATO members would help the US if it were attacked. This is the lowest level of confidence among the 32 member countries, and the overall average for the alliance has dropped by eight percentage points since 2025. Although most people still think the partnership is important, there is a clear change in opinion. For instance, positive views of Russia and China have risen to 17% and 22%, while support for Ukraine has fallen to 55%.

一項針對超過 31,000 人的調查顯示，僅有 43% 的美國成年人相信如果美國受到攻擊，其他北約成員國會提供協助。這是 32 個成員國中最低的信心水平，且整個聯盟的平均值自 2025 年起已下降了 8 個百分比點。雖然大多數人仍認為此夥伴關係至關重要，但觀點已明顯改變。例如，對俄羅斯和中國的正面看法分別上升至 17% 和 22%，而對烏克蘭的支持則下降至 55%。

Analysts emphasize that this change is caused by the ongoing criticisms from President Donald Trump. The administration has described the alliance as unfair, arguing that there is a large difference in defense spending between the US and European members. Furthermore, tensions grew after NATO members refused to support the purchase of Greenland and denied US aircraft access to airspace and bases during operations against Iran. Consequently, Secretary of War Pete Hegseth has started a six-month review of US military presence in Europe, stating that future funding and deployments depend on whether Washington's demands are met. While some leaders believe these criticisms are meant to encourage Europe to spend more on defense, other experts suggest there may be different strategic goals.

分析師強調，這一變化是由總統川普持續的批評所引起。政府將該聯盟描述為不公平，認為美國與歐洲成員國在國防開支方面存在巨大差異。此外，在北約成員國拒絕支持購買格陵蘭，以及在針對伊朗的行動期間拒絕美國飛機進入領空和基地後，緊張局勢隨之增加。因此，戰爭部長 Pete Hegseth 已開始對美國在歐洲的軍事部署進行為期六個月的審查，並表示未來的資金和部署取決於華盛頓的要求是否得到滿足。雖然部分領導人認為這些批評旨在鼓勵歐洲增加國防開支，但其他專家建議，其中可能包含不同的戰略目標。

US support for NATO's collective defense has reached a record low due to disagreements over spending and strategic cooperation.

由於在開支與戰略合作方面存在分歧，美國對北約集體防禦的支持率已跌至歷史最低點。
