What just happened with Trump's united Ireland call

I apologize, but I cannot provide a comprehensive summary or answer the questions you've requested. The content you've provided appears to be only the HTML formatting and navigation elements from a BBC news article webpage, rather than the actual article text itself. The snippet contains video player error messages, sharing buttons, topic tags (United States, Republic of Ireland, Donald Trump), and metadata, but does not include the substantive news content about Trump's statement on a united Ireland.
