While the term “Trump-led diplomacy” likely refers to a time when Donald Trump was the president of the United States, the exact context or news event that you are referring to is not clear. From 2017 to 2021, Trump’s administration saw a number of policy changes including how the US dealt with Ukraine and its challenges with Russia. Trump’s approach could be seen as controversial, often causing disagreements among Ukraine’s other allies, particularly in Europe.
If you are referring to a specific event or recent news, I would appreciate more information so I can provide a more satisfactory response. What is certain is that international diplomacy is often complex, with many factors affecting relationships at any given time.
