Passage: In 2014, Ivanovic enjoyed a resurgence and attained a number of career-best achievements. She began the year by winning her first title in three years at the ASB Classic, defeating former world No. 1 Venus Williams in three sets before upsetting the reigning world No. 1 Serena Williams en route to her second Australian Open quarterfinal where she lost in three sets to thirtieth seed, Eugenie Bouchard. During the clay court season, Ivanovic reached her third final of the year at the Porsche Tennis Grand Prix, losing to two-time defending champion Maria Sharapova; the quarterfinals of the Mutua Madrid Open and the semi-finals of the Internazionali BNL d'Italia, defeating Sharapova for the first time since 2007 en route but was ultimately upset by Lucie Šafářová in the third round of the French Open. She rebounded by winning her first career singles title on grass at the Aegon Classic before reaching the final of the Western & Southern Open (her first top tier Premier final since 2009) and thus returned to the top ten of the WTA rankings for the first time in five years as a result. In September, Ivanovic reached her sixth singles final of the year (a new career-best) at the Toray Pan Pacific Open, where she defeated Caroline Wozniacki to claim her fourth title of the season, the most titles she won in a single season.

Passage: In the immediate aftermath of World War II, the leadership of the Soviet Union feared the United States would use its nuclear superiority to its advantage, as from 1945 to 1948 the U.S. was the only state possessing nuclear weapons. The USSR countered by rapidly developing their own nuclear weapons, surprising the US with their first test in 1949. In turn, the U.S. countered by developing the vastly more powerful thermonuclear weapon, testing their first hydrogen bomb in 1952 at Ivy Mike, but the USSR quickly countered by testing their own thermonuclear weapons, with a test in 1953 of a semi-thermonuclear weapon of the Sloika design, and in 1956, with the testing of Sakharov's Third Idea – equivalent to the Castle Bravo device. Meanwhile, tensions between the two nations rose as 1956 saw the suppression of Hungary by the Soviets; the U.S. and European nations drew certain conclusions from that event, while in the U.S., a powerful social backlash was afoot, prompted by Senator Joseph McCarthy, the House Un-American Activities Committee, and Julius and Ethel Rosenberg, U.S. citizens executed in 1953 after conviction of espionage. This atmosphere was further inflamed by the 1957 launch of Sputnik, which led to fears of Communists attacking from outer space, as well as concerns that if the Soviets could launch a device into orbit, they could equally cause a device to re-enter the atmosphere and impact any part of the planet. John F. Kennedy capitalized on this situation by emphasizing the Bomber gap and the Missile gap, areas in which the Soviets were (inaccurately) perceived as leading the United States, while heated Soviet rhetoric added to political pressure. The 1960 U-2 incident, involving Francis Gary Powers, as well as the Berlin Crisis, along with the test of the Tsar Bomba, escalated tensions still further.
