The original source from Bluesky isn't avalibale but the article from the Political reveals the expanded information:
https://www.politico.eu/article/war-iran-ukraine-pull-europe-us-apart/ Politico is a prominent American political journal that focuses on US and international politics. While the Journal originated in the US, a German media company later bought it, and the primary headquarters is located in Brussels. Due to the company's current owners and headquarters, the political journal mainly focuses on the European perspective. The author of the article, Nicolas Vinocur, is the Chief Foreign Affairs Correspondent for Politico. Given his senior position and professional background, he is generally considered a reliable journalist. However, particular parts of the article contain quotes from diplomats regarding the tensions between the US and European leaders, but he keeps his sources anonymous by referring to them as "one diplomat said." This requires the reader to trust the journalists intergretty and access to high-position leaders.
The core premise of the information appears to be true: European leaders are concerned about potential retaliation from Donald Trump and the US regarding future funding for Ukraine if they don't support the US-Israel conflict in Iran. While leaders are concerned they aren't "panicking" over potential U.S policy shifts with Donald Trump, this tension is further complicated by the US pressue on its allies to back their military campaign against Iran, under the threat of diplomatic consequences. In the Time, a mainstream news source claimed Trump is considering pulling out of NATO if European countries won't back the US military campaign, which aligns with the Politico article that EU leaders are being pressured to align with the US. time.com/article/2026/04/01/trump-considering-pulling-us-out-of-nato-iran-war-legal-options/. The article from the Politico is based on an interview from a unamed diplomat. This indicates that the information is from an inside source, but since they are anonymous, their credibility cannot be verified. The claim is based on an unverified statement, which forces the reader to trust the journalist.
