Question: Was the SPD larger than the DDP the year the Weimar Coalition stopped dominating German politics? Passage 1:As an amateur, Doherty won the Irish Amateur Championship twice, the World Under-21 Amateur Championship and the World Amateur Championship. Having turned professional in 1990, Doherty has won a total of six ranking tournaments, including the 1997 World Snooker Championship in which he defeated Stephen Hendry, inflicting Hendry's first loss in a world final. This made him the first player, and so far one of only two (the other being Stuart Bingham) to have been world amateur and professional champion. The following year, he came very close to breaking the Crucible curse, reaching the 1998 final where he lost out to John Higgins. He reached a third final in 2003, in which he was defeated by Mark Williams. In other triple crown events, he is a three-time UK Championship runner-up and a two-time Masters runner-up.
Passage 2:The Israeli historian Yehuda Bauer wrote that Goldhagen's thesis about a murderous antisemitic culture applied better to Romania than to Germany and murderous anti-Semitism was not confined to Germany as Goldhagen had claimed. Bauer wrote of the main parties of the Weimar Coalition that dominated German politics until 1930, the leftist SPD and the liberal DDP were opposed to anti-Semitism while the right-of-the-centre Catholic Zentrum was "moderately" antisemitic. Bauer wrote of the major pre-1930 political parties, the only party that could be described as a radically antisemitic was the conservative German National People's Party, who Bauer called "... the party of the traditional, often radical anti-Semitic elites..." who were "... a definite minority" while the NSDAP won only 2.6% of the vote in the Reichstag elections in May 1928. Bauer charged that it was the Great Depression, not an alleged culture of murderous anti-Semitism that allowed the NSDAP to make its electoral breakthrough in the Reichstag elections of September 1930.
Passage 3:It is widely believed that Saudi Arabia has been a major financier of Pakistan's own integrated atomic bomb project since 1974, a programme founded by former prime minister Zulfikar Ali Bhutto. In the 1980s, Chief Martial Law Administrator and President General Zia-ul-Haq paid a state visit to Saudi Arabia where he unofficially told the King that: "Our achievements are yours". This cooperation was allegedly furthered by socialist prime minister Benazir Bhutto in 1995. In 1998, the conservative Prime minister Nawaz Sharif informed Saudi Arabia confidentially before ordering the nuclear tests (see Chagai-I and Chagai-II) in the Weapon-testing labs-III (WTL) located in the Chagai remote site in Balochistan Province of Pakistan. In June 1998, the Prime Minister paid a farewell visit to King Fahd and publicly thanked the Saudi government for supporting the country after the tests. Shortly thereafter, Saudi Minister of Defense Prince Sultan went with Prime Minister Sharif on a tour of a classified institute, the Kahuta Research Laboratories (KRL), where leading scientist Abdul Qadeer Khan briefed the Prince and Prime Minister Sharif on nuclear physics and sensitive issues involving nuclear explosive devices.
