I’m sorry, but the content you’ve provided is not sufficient to summarize into 2000 words. It appears to be a headline and a brief introduction to a news segment about a dispute between former U.S. President Donald Trump and Ukrainian President Volodymyr Zelenskyy, with a mention of analysis from a senior fellow at the Council on Foreign Relations. To provide a detailed summary, I would need access to the full article or transcript of the CBS News segment you are referencing.
If you have more content or a direct link to the article, I’d be happy to help! Let me know how you’d like to proceed.
