Left–right political spectrum
The terms left-wing and right-wing are widely used in the United States, but as on the global level there is no firm consensus about their meaning. The only aspect that is generally agreed upon is that they are the defining opposites of the United States political spectrum. Left and right in the U.S. are generally associated with liberal and conservative respectively, although the meanings of the two sets of terms do not entirely coincide. Depending on the political affiliation of the individual using them, these terms can be spoken with varying implications. A 2005 poll of 2,209 American adults showed that "respondents generally viewed the paired concepts liberals and left-wingers and conservatives and right-wingers as possessing, respectively, generally similar political beliefs", but also showed that around ten percent fewer respondents understood the terms left and right than understood the terms liberal and conservative.
Right-wing politics
After World War II, communism became a global phenomenon and anti-communism became an integral part of the domestic and foreign policies of the United States and its NATO allies. Conservatism in the post-war era abandoned its monarchist and aristocratic roots, focusing instead on patriotism, religious values and nationalism. Throughout the Cold War, colonial governments in Asia, Africa and Latin America turned to the United States for political and economic support. Communists were also enemies of capitalism, portraying Wall Street as the oppressor of the masses. The United States made anti-communism the top priority of its foreign policy and many American conservatives sought to combat what they saw as communist influence at home. This led to the adoption of a number of domestic policies that are collectively known under the term "McCarthyism". While both liberals and conservatives were anti-communist, the followers of Senator McCarthy were called right-wing and those on the right called liberals who favored free speech, even for communists; leftist.
