Recent data from the Pew Research Center and the Lowy Institute indicate a substantial decrease in international confidence regarding the United States and the leadership of President Donald Trump.

皮尤研究中心與洛威研究所的最新數據顯示，國際社會對美國以及總統川普領導層的信心大幅下降。

The Pew Research Center's survey of 42,151 adults across 36 nations, conducted between February and May 2026, reveals a systemic deterioration in the perceived reliability of the United States as a global partner. This trend is particularly pronounced among traditional allies. In Australia, the proportion of citizens viewing the U.S. as a dependable partner declined to 37%, a significant contraction from the 79% recorded in 2022. Similarly, Canadian sentiment shifted from 83% reliability in 2022 to 35% in 2026, a decline attributed to the implementation of tariffs and annexation threats. Within Europe, confidence has diminished by 28 to 52 percentage points across eight nations, with Germany experiencing a collapse in the belief that Washington considers foreign interests, falling from 60% in 2023 to 23%.

皮尤研究中心在2026年2月至5月期間，對36個國家的42,151名成年人進行了調查，結果顯示美國作為全球合作夥伴的可靠性正在系統性惡化。這一趨勢在傳統盟友之中尤為明顯。在澳洲，認為美國是可靠夥伴的公民比例下降至37%，較2022年記錄的79%大幅縮減。同樣地，加拿大的觀感從2022年的83%可靠性下降至2026年的35%，此一下降歸因於關稅的實施與併吞威脅。在歐洲，八個國家的信心水平下降了28至52個百分點，其中德國對於「華盛頓會考慮外國利益」的信念崩潰，從2023年的60%跌至23%。

Stakeholder positioning regarding President Donald Trump's efficacy in global affairs is predominantly negative. A median of 76% of global respondents expressed a lack of confidence in the President's capacity to act appropriately in international matters. In Australia, this figure reached 82%, resulting in a confidence rating (18%) lower than that of Chinese President Xi Jinping (23%). Globally, Trump's trust ratings were surpassed by leaders such as Emmanuel Macron, Volodymyr Zelenskyy, and Vladimir Putin. Conversely, higher levels of confidence were maintained in the Philippines, Israel, Nigeria, Kenya, and Ghana.

利益相關者對總統川普處理全球事務能力的定位基本上是負面的。全球受訪者的中位數有76%表示對總統在國際事務上採取適當行動的能力缺乏信心。在澳洲，這一數字達到82%，導致其信心評分（18%）低於中國國家主席習近平（23%）。在全球範圍內，川普的信任評分被 Emmanuel Macron、Volodymyr Zelenskyy 及 Vladimir Putin 等領導人超越。相反，菲律賓、以色列、尼日利亞、肯亞及迦納則維持較高水平的信心。

Specific policy initiatives have further exacerbated this diplomatic friction. Global disapproval is concentrated on the administration's handling of the conflict in Gaza (76%), relations with Iran (74%), and the application of tariffs (77%), with the latter seeing opposition rates as high as 92% in Germany. These sentiments correlate with a decline in leisure travel to the U.S.; Australian tourism arrivals decreased by 9.2% in the first five months of 2026, mirroring broader declines in visitors from Italy, France, and Germany. Notably, Danish arrivals fell by 30% following the administration's expressed interest in the acquisition of Greenland for national security purposes. Despite these negative perceptions, the Lowy Institute notes that approximately three-quarters of Australians continue to regard the U.S. alliance as significant for national security.

特定的政策舉措進一步加劇了這些外交摩擦。全球的不滿集中在政府對加薩衝突的處理（76%）、與伊朗的關係（74%）以及關稅的應用（77%），而後者在德國的反對率高達92%。這些情緒與前往美國的休閒旅遊人數下降相關；2026年前五個月，澳洲的遊客到達人數減少了9.2%，反映了來自義大利、法國及德國訪客的整體下降。值得注意的是，在政府表達對以國家安全為目的收購格陵蘭的興趣後，丹麥的抵達人數下降了30%。儘管有這些負面觀感，洛威研究所指出，約四分之三的澳洲人仍認為美國同盟對國家安全至關重要。

The United States is currently experiencing a widespread decline in international trust and diplomatic favor, though strategic security alliances remain largely intact.

美國目前正經歷國際信任與外交好感度的普遍下降，但策略性安全同盟基本上仍維持完好。
