Politics is the process and method of gaining or maintaining support for public or common action, the conduct of decision-making for groups. Although it is usually applied to governments, political behavior is also observed in corporate, academic, religious, and other institutions. Political philosophy is the study of topics such as politics, liberty, justice, property, rights, law, and the enforcement of a legal code by authority: what they are, why (or even if) they are needed, what, if anything, makes a government legitimate, what rights and freedoms it should protect and why, what form it should take and why, what the law is, and what duties citizens owe to a legitimate government, if any, and when it may be legitimately overthrown, if ever. Political science is the field devoted to studying political behavior and examining the acquisition and application of power, or the ability to impose one's will on another. Its practitioners are known as political scientists. Political scientists look at elections, public opinion, institutional activities, the ideologies behind various politicians and interest groups, how politicians achieve and wield their influence, and so on.
The Power of Nightmares is a BBC documentary film series, written and produced by Adam Curtis. The series consists of three one-hour films, consisting mostly of a montage of archive footage with Curtis's narration, which were first broadcast in the United Kingdom in late 2004 and have been subsequently aired in multiple countries and shown in several film festivals, including the 2005 Cannes Film Festival. The films compare the rise of the American Neo-Conservative movement and the radical Islamist movement, making comparisons on their origins and noting strong similarities between the two. More controversially, it argues that the threat of radical Islamism as a massive, sinister organised force of destruction, specifically in the form of al-Qaeda, is in fact a myth perpetrated by politicians in many countries—and particularly American Neo-Conservatives—in an attempt to unite and inspire their people following the failure of earlier, more utopian ideologies. The Power of Nightmares has been praised by film critics in both Britain and the United States. Its message and content have also been the subject of various critiques and criticisms from conservatives and progressives.
