Question:
Xenomania is an English songwriting and production team founded by Brian Higgins and based in Kent, England. Formed after Higgins met Miranda Cooper, Xenomania has written and produced for renowned artists such as Cher, Kylie Minogue, Dannii Minogue, Sophie Ellis-Bextor, Pet Shop Boys, The Saturdays and the Sugababes. In particular, all but one of Girls Aloud's studio albums have been entirely written and produced by Xenomania. Sugababes' "Round Round" and Girls Aloud's "Sound of the Underground" have been credited with reshaping British pop music for the 2000s.
Xenomania worked with American pop singer Britney Spears in 2003 during sessions for her fourth album In the Zone. The song submitted, "Graffiti My Soul", was not chosen for the album. While the record company loved the song, Spears felt that it needed more of a chorus. Higgins said that they wanted "essentially 'Sound of the Underground 2'." It later appeared on Girls Aloud's What Will the Neighbours Say?.  The production team were due to work with rock bands New Order and Franz Ferdinand, but both sessions proved fruitless. Xenomania was due to produce for New Order's Waiting for the Sirens' Call, but Peter Hook said they "scrapped the Brian Higgins stuff because we didn't like it. I thought he did quite a good job on Girls Aloud but he didn't do a good job on us." Franz Ferdinand's drummer Paul Thomson said, "We wrote with Higgins for a while and initially we thought we'd work more with him but it didn't really work out. We just realized that we're not really a pop group."  Xenomania were reported to have written five songs for Leona Lewis's second album, Echo (2009), described by Cooper as "tragic songs with a twist". The songs did not make the album. In 2012, Xenomania were reported to be working with Christina Aguilera.  Higgins spoke of bad experiences with bigger artists to Literally magazine in 2009:  "Everything about us is about enormous enthusiasm for something. And therefore big artists can come in and they think "they're the flavour of the whatever, let's take their thing and then we'll do what we want with it..." Well, no, that's not acceptable anyway. I've had that experience happen where the big artists were fine until they got into the mix room and then they basically pulled the record to pieces. So I took my name off the record and the writing credits off the record. Because they're assholes. And they sold about 20,000 copies, and they've never been seen since. So big artists are often jerks of the biggest order. And often people say don't meet your heroes because you'll be let down, and I sort of understand why people would say that."

Answer the question at the end by quoting:

Richard Milhous Nixon was born on January 9, 1913 in Yorba Linda, California, in a house that was built by his father. His parents were Hannah (Milhous) Nixon and Francis A. Nixon. His mother was a Quaker, and his father converted from Methodism to the Quaker faith. Nixon was a descendant of the early American settler, Thomas Cornell, who was also an ancestor of Ezra Cornell, the founder of Cornell University, as well as of Jimmy Carter and Bill Gates.
Nixon used the improving international environment to address the topic of nuclear peace. Following the announcement of his visit to China, the Nixon administration concluded negotiations for him to visit the Soviet Union. The President and First Lady arrived in Moscow on May 22, 1972 and met with Leonid Brezhnev, the General Secretary of the Communist Party; Alexei Kosygin, the Chairman of the Council of Ministers; and Nikolai Podgorny, the head of state, among other leading Soviet officials.  Nixon engaged in intense negotiations with Brezhnev. Out of the summit came agreements for increased trade and two landmark arms control treaties: SALT I, the first comprehensive limitation pact signed by the two superpowers, and the Anti-Ballistic Missile Treaty, which banned the development of systems designed to intercept incoming missiles. Nixon and Brezhnev proclaimed a new era of "peaceful coexistence". A banquet was held that evening at the Kremlin.  Seeking to foster better relations with the United States, both China and the Soviet Union cut back on their diplomatic support for North Vietnam and advised Hanoi to come to terms militarily. Nixon later described his strategy:  I had long believed that an indispensable element of any successful peace initiative in Vietnam was to enlist, if possible, the help of the Soviets and the Chinese. Though rapprochement with China and detente with the Soviet Union were ends in themselves, I also considered them possible means to hasten the end of the war. At worst, Hanoi was bound to feel less confident if Washington was dealing with Moscow and Beijing. At best, if the two major Communist powers decided that they had bigger fish to fry, Hanoi would be pressured into negotiating a settlement we could accept.  Having made considerable progress over the previous two years in U.S.-Soviet relations, Nixon embarked on a second trip to the Soviet Union in 1974. He arrived in Moscow on June 27 to a welcome ceremony, cheering crowds, and a state dinner at the Grand Kremlin Palace that evening. Nixon and Brezhnev met in Yalta, where they discussed a proposed mutual defense pact, detente, and MIRVs. While he considered proposing a comprehensive test-ban treaty, Nixon felt he would not have time as president to complete it. There were no significant breakthroughs in these negotiations.

was the negotiation successful?
