The 1960 Four Power Paris Summit between President Dwight Eisenhower, Nikita Khrushchev, Harold Macmillan and Charles de Gaulle collapsed because of the incident. Eisenhower refused to accede to Khrushchev's demands that he apologize. Therefore, Khrushchev would not take part in the summit. Up until this event, Eisenhower felt he had been making progress towards better relations with the Soviet Union. Nuclear arms reduction and Berlin were to have been discussed at the summit. Eisenhower stated it had all been ruined because of that "stupid U-2 business".
Along with reducing nuclear weapons, what was to have been the topic of conversation at the Four Power Paris Summit?

The opinion of the majority of Croatian linguists[citation needed] is that there has never been a Serbo-Croatian language, but two different standard languages that overlapped sometime in the course of history. However, Croatian linguist Snježana Kordić has been leading an academic discussion on that issue in the Croatian journal Književna republika from 2001 to 2010. In the discussion, she shows that linguistic criteria such as mutual intelligibility, huge overlap in linguistic system, and the same dialectic basis of standard language provide evidence that Croatian, Serbian, Bosnian and Montenegrin are four national variants of the pluricentric Serbo-Croatian language. Igor Mandić states: "During the last ten years, it has been the longest, the most serious and most acrid discussion (…) in 21st-century Croatian culture". Inspired by that discussion, a monograph on language and nationalism has been published.

Victoria later described her childhood as "rather melancholy". Her mother was extremely protective, and Victoria was raised largely isolated from other children under the so-called "Kensington System", an elaborate set of rules and protocols devised by the Duchess and her ambitious and domineering comptroller, Sir John Conroy, who was rumoured to be the Duchess's lover. The system prevented the princess from meeting people whom her mother and Conroy deemed undesirable (including most of her father's family), and was designed to render her weak and dependent upon them. The Duchess avoided the court because she was scandalised by the presence of King William's bastard children, and perhaps prompted the emergence of Victorian morality by insisting that her daughter avoid any appearance of sexual impropriety. Victoria shared a bedroom with her mother every night, studied with private tutors to a regular timetable, and spent her play-hours with her dolls and her King Charles spaniel, Dash. Her lessons included French, German, Italian, and Latin, but she spoke only English at home.
