Elizabeth II is friends with many world leaders. Her first Prime Minister of Australia, Sir Robert Menzies called her "My Dear" and recited a poem that said "I will love her till I die". She has friendships with Mary Robinson, President of Ireland (1990-1997) and George W. Bush, who was the first American President in more than 80 years to stay at Buckingham Palace. Nelson Mandela, in a BBC documentary, called her "my friend, Elizabeth".
