input: In 1923, after the failed Beer Hall Putsch, Hitler, who had been imprisoned for treason, appointed Rosenberg as the leader of the National Socialist movement, a position he held until Hitler's release. Hitler remarked privately in later years that his choice of Rosenberg, whom he regarded as weak and lazy, was strategic; Hitler did not want the temporary leader of the Nazis to become too popular or hungry for power, because a person with either of those two qualities might not want to cede the party leadership after Hitler's release. However, at the time of the appointment Hitler had no reason to believe that he would soon be released, and Rosenberg had not appeared weak, so this may have been Hitler reading back into history his dissatisfaction with Rosenberg for the job he did.  In 1929 Rosenberg founded the Militant League for German Culture. He later formed the "Institute for the Study of the Jewish Question," dedicated to identifying and attacking Jewish influence in German culture and to recording the history of Judaism from a radical nationalist perspective. He became a Reichstag Deputy in 1930 and published his book on racial theory The Myth of the Twentieth Century (Der Mythus des 20. Jahrhunderts) which deals with key issues in the National Socialist ideology, such as the "Jewish question." Rosenberg intended his book as a sequel to Houston Stewart Chamberlain's above-cited book.  Despite selling more than a million copies by 1945, its influence within Nazism remains doubtful. It is often said to have been a book that was officially venerated within Nazism, but one that few had actually read beyond the first chapter or even found comprehensible. Hitler called it "stuff nobody can understand" and disapproved of its pseudo-religious tone.  Rosenberg convinced Hitler that communism was an international threat due to the fragility of the Soviet Union's internal political structure. "Jewish-Bolshevism" was accepted as a target for Nazism during the early 1920s.  In Rome during November 1932 Rosenberg participated in the Volta Conference. British historian Sir Charles Petrie met him there and regarded him with great distaste; Petrie was a Catholic and strongly objected to Rosenberg's anti-Jewish and anti-Catholic sentiments.  The following year, once Hitler had become Chancellor, Rosenberg was named leader of the Nazi Party's foreign political office, but he played little practical part in the role. Another event of 1933 was Rosenberg's visit to Britain, intended to give the impression that the Nazis would not be a threat and to encourage links between the new regime and the British Empire. It was a notable failure. When Rosenberg laid a wreath bearing a swastika at the Cenotaph, a Labour Party candidate slashed it and later threw it in the Thames and was fined 40 shillings for willful damage at Bow Street magistrate's court. In January 1934 Hitler granted Rosenberg responsibility for the spiritual and philosophical education of the Party and all related organizations.

input: Rafferty was fired from the band on 31 January 2008, after a series of absences due to illness and long-standing rumours about his place in the band; drug addiction was also quoted as one of the reasons for his departure. Rafferty subsequently refuted these claims, saying that he had been fired from the band because he "didn't think Konk was very good, and I said that." Dan Logan, bassist with a local Brighton band Cat the Dog, was drafted in as a temporary replacement for Rafferty. After the departure of Rafferty, the band had considered splitting up. Singer Luke Pritchard had told The Sun's Something for the Weekend that "Splitting does go through your mind. It's hard to let go of something you care about so much. We have fans to think of." Pritchard also discussed the possibility of Dan Logan joining the band as their new bassist, "It's been really strange for us but it's something that had to happen. Dan hasn't joined the band properly yet. We're trying him out, but I love playing with him." In October 2008, Peter Denton - who had previously filled in for Rafferty during the Inside In/Inside Out touring cycle - was chosen as the permanent bassist.  The Kooks released their second album, Konk, in April 2008. The record was named after the studio where it was recorded and produced by Tony Hoffer, who worked on the band's debut album, Inside In/Inside Out. Prior to releasing the album, in an interview with NME, lead singer Luke Pritchard had claimed to have 80-90 songs written for the album, stating, "I want this album to be big......I've got an ego, I want the album to do well. I want our singles to come on the radio and for people to literally have their heads blown off by them". Recorded over a total of seven weeks in London and Los Angeles Pritchard told NME the band had wanted more input into their second album. "Tony's a genius, but this time we wanted more involvement in the production," said Pritchard.  Konk went on to debut on the UK Albums Chart at number one with first week sales of 65,901 units. The album also spawned three top 50 hits including their highest chart performer to date, "Always Where I Need to Be", which peaked at number three. In the United States, it reached number 41 on the Billboard 200 and the album's first single, "Always Where I Need to Be", peaked at number 22 on the Alternative Songs chart. The album was certified gold in both the UK and Ireland. A second limited edition two disc version of Konk entitled RAK was also released. The name was taken from the London studio where The Kooks recorded seven new live tracks along with the Arctic Monkeys and Mike Crossey, producer for The Zutons.  Allmusic said with Konk, The Kooks "explores pop and rock in all their glory," while BBC Music described their second album as "a little contrived with the recycling of old guitar lines and intros." NME suggested the departure of Rafferty affected Konk's production, stating "Konk is the sound of a band in disarray, unsuccessfully attempting to hold things together."
