Input: Question: In which country did Whittaker Chambers went to war as a U.S. Army Lieutenant? Passage:Novak was registered Democrat, despite his conservative political views. He held more centrist views in his early career, and he supported the Democratic presidential candidacies of John F. Kennedy and Lyndon B. Johnson, of whom he was a friend. In later years, he said that he maintained his registered Democratic status so he could vote in District of Columbia Democratic primaries where victory would be tantamount to election. He was also close friends with Everett Dirksen. Novak later stated that reading Whittaker Chambers' book Witness changed his views from moderate-to-liberal to a strident anticommunism. Reading Chambers' message as a U.S. Army lieutenant in the Korean War gave him a feeling of moral absolutism in his cause. Novak's views turned further rightward through the 1970s, but Novak remained strongly critical toward Ronald Reagan and his supply side economics in the early 1980s. Novak changed his mind after debating economics with Reagan face to face, and he later wrote that Reagan was one of the very few politicians that he ever respected.
