Sorry, but you simply don’t know what you are talking about. This has been discussed to death on this forum, too bad you came in late.
By the way, I don’t dispute any of the FACTS you have, only that you don’t have enough of them. For example, the fact that I do not and never have harbored any doubts about Donald Trumps natural born citizenship.
But YOU need to know that Mrs. Trump’s naturalization in 1944 has NO BEARING whatsoever on the issue as framed.
Why? Simple, because Britain does not and has never recognized any renunciation of citizenship unless made in the proper form and manner to the British Home Secretary. Naturalization in another country is not recognized in Britain as an effective renunciation of citizenship. The law on this is clear, and the fact that you don’t know it is immaterial.
