Question: Who is defense minister of the country where the author of The Doctor's Dilemma was a citizen?

full_context: Document 1: The Devil's Disciple: The Devil's Disciple is an 1897 play written by Irish dramatist George Bernard Shaw. The play is Shaw's eighth, and after Richard Mansfield's original 1897 American production it was his first financial success, which helped to affirm his career as a playwright. It was published in Shaw's 1901 collection "Three Plays for Puritans" together with "Captain Brassbound's Conversion" and "Caesar and Cleopatra". Set in Colonial America during the Revolutionary era, the play tells the story of Richard Dudgeon, a local outcast and self-proclaimed "Devil's disciple". In a twist characteristic of Shaw's love of paradox, Dudgeon sacrifices himself in a Christ-like gesture despite his professed Infernal allegiance.

The play has often been interpreted as a kind of satirical commentary on Shaw's own highly successful earlier play "Candida" (which one of the characters gets tickets to see).
Document 15: The Importance of Being Earnest: After the success of Wilde's plays Lady Windermere's Fan and A Woman of No Importance, Wilde's producers urged him to write further plays. In July 1894 he mooted his idea for The Importance of Being Earnest to George Alexander, the actor - manager of the St James's Theatre. Wilde spent the summer with his family at Worthing, where he wrote the play quickly in August. His fame now at its peak, he used the working title Lady Lancing to avoid pre-emptive speculation of its content. Many names and ideas in the play were borrowed from people or places the author had known; Lady Queensberry, Lord Alfred Douglas's mother, for example, lived at Bracknell. There is widespread agreement among Wilde scholars that the most important influence on the play was W.S. Gilbert's 1877 farce Engaged; Wilde borrowed from Gilbert not only several incidents but, in Russell Jackson's phrase ``the gravity of tone demanded by Gilbert of his actors ''.
