This paper takes the case of the Irish Republican Socialist Movement (IRSM) as the point of departure to discuss how insurgent political movement use Web communications. From mirror sites in Ireland and North America, IRSM supporters regularly use Web technology to relay the group message to a global audience at http://www.irsm.org/irsm.html. The resulting direct media contact gives the IRSM unprecedented access to global civil society. By referring to the IRSM Web site, the types of messages transmitted, the forms of transmission (text, video, audio, e-mail or other), and target audiences (national, global, political elites, media), this paper outlines some of the issues and challenges posed by Web-based anti-government media. The Internet and the Web do not constitute a threat to state power as some analysts suggest but at the same time they significantly alter political communication. The IRSM is a case of “enationalism”, that is, the representation of a place as home to a specific group of people. Unlike traditional nationalism, enationalism is not tied to physical space or territory, but to representation of a network of relations based on a common language, historical experience, religion and/or culture. It is about both memory and future projection of a place as the home for a given group. In this light, new media will likely co-exist with other forms of political communication for some time.

New communication technologies are often invested with users’ hopes for change in the social order. Thus the Internet is said to be inherently democratic, levelling traditional distinctions of social status, and creating opportunities for less powerful individuals and groups to participate on a par with members of more powerful groups. Specifically, the Internet has been claimed to lead to greater gender equality, with women, as the socially, politically, and economically less powerful gender, especially likely to reap its benefits.

Usually the Internet is seen as a new medium with great potential for enhancing citizenship and democracy. This essay will try to present and to reflect on some of the less well known sides of the world wide web. In this case the ‘dark sides’ of the Internet will not refer to web sites of sex and violence, which have attracted more attention, but rather to two political movements with a high presence in the Internet: on the one hand the neoNazis in Germany and elsewhere, and on the other hand the Taliban in Afghanistan. At first glance a topic like the ‘neo-Nazis and Taliban on-line’ seems to combine very disparate societal movements that are neither new (the Nazis) nor very active in a modern environment (the Taliban). This contribution will show that both the neo-Nazis and the Taliban have important similarities in their structural approaches to society as well as in their presence in the Internet, but there are also of course serious differences. Because of this unusual comparison it will be helpful to sketch some of the context for the activities of the neo-Nazis and Taliban before we turn to the main issue.

The purpose of this paper is to explore the role of interest groups in the formation of online echo chambers and to determine whether interest groups’ use of social media contributes to political polarization.

This study used a content analysis of nearly 10,000 tweets (from 2009 to 2014) by the Brady Campaign to Prevent Gun Violence and the National Rifle Association to examine how groups engage with their political allies and opponents.

The results indicated that both groups engaged primarily with their supporters on Twitter while avoiding confrontation with their opponents. In particular, both groups used hashtags designed to reach their supporters, retweeted messages almost exclusively from other users with whom they agreed, and disproportionately used Twitter handles of their allies, while avoiding the use of Twitter handles of their opponents.

The findings suggest that interest groups’ use of social media accelerates the formation of online echo chambers, but does not lead to an increase in polarization beyond existing levels, given practices that maintain civility between opposing sides.

In this paper we use methods of social network analysis to examine the inter-organizational structure of the white supremacist movement. Treating links between Internet websites as ties of affinity, communication, or potential coordination, we investigate the structural properties of connections among white supremacist groups. White supremacism appears to be a relatively decentralized movement with multiple centers of influence, but without sharp cleavages between factions. Interorganizational links are stronger among groups with a special interest in mutual affirmation of their intellectual legitimacy (Holocaust revisionists) or cultural identity (racist skinheads) and weaker among groups that compete for members (political parties) or customers (commercial enterprises). The network is relatively isolated from both mainstream conservatives and other extremist groups. Christian Identity theology appears ineffective as a unifying creed of the movement, while Nazi sympathies are pervasive. Recruitment is facilitated by links between youth and adult organizations and by the propaganda efforts of more covertly racist groups. Links connect groups in many countries, suggesting the potential of the Internet to facilitate a whitesupremacist “cyber-community” that transcends regional and national boundaries.

The number of people connecting to the Internet is growing at an astounding rate: estimates range from 100% to 400% annually over the next five years. This unprecedented level of interconnectedness has brought with it the specter of a new threat: cyberterrorism. This thesis examines the impact of this threat on the critical infrastructure of the United States specifically focusing on Department of Defense issues and the National Information Infrastructure (NII). A working definition for cyberterrorism is derived, and a description of the Nation’s critical infrastructure is provided. A number of possible measures for countering the threat of cyberterrorism are discussed, with particular attention given to the concept of information assurance.

Information assurance demands that trustworthy systems be developed from untrustworthy components within power-generation systems, banking, transportation, emergency services, and telecommunications. The importance of vulnerability testing (or red-teaming) is emphasized as part of the concept of information assurance. To support this, a cyberterrorist ‘red team’ was formed to participate in the Marine Corps’ Urban Warrior Experiment. The objective of t his thesis is to address the impact of these issues from a Systems Management perspective. This includes taking into account the changes that must occur in order to improve the U.S.’ ability to detect, protect against, contain, neutralize, mitigate the effects of, and recover from attacks on the Nation’s Critical Infrastructure.
