Rohan Gunaratna, head of the International Centre for Political violence and Terrorism Research at the S Rajaratnam School of International Studies in Singapore, writes: 'Due to international neglect and tolerance of threat groups on the web, propaganda is now the primary activity of insurgent, terrorist and extremist groups. Almost all threat groups worldwide have established a presence on the web, and over 90 percent of them use US servers. They are expanding their web presence at a rate where governments find it hard to keep up, both to counter disinformation and to monitor operational activity. Although dissent must be permitted, maintaining websites and blogs aimed at radicalising youth under the pretext of freedom of expression should not be tolerated. Cyberspace has emerged as the principal propaganda platform for threat groups to recruit, raise funds and to coordinate operations.'
