The Hague Centre for Strategic Studies

HCSS (Netherlands)

The Hague Centre for Strategic Studies (HCSS) was established in 2007 as an independent think tank. The founder Prof. dr. Rob de Wijk started this organization with a small team of senior experts and analysts, being drawn in from organizations such as the Netherlands Organisation for Applied Scientific Research (TNO), RAND, Clingendael, the Dutch Ministry of Defense and the United Nations. This team has been conducting strategic research and analyses on issues of international and national security and defense. It translated conceptual thinking into solution-oriented policy and operational recommendations with its partners.
Over the past years, HCSS has expanded its size, scope and reputation. It is now a well-known organization, linking the security domain to issues on social economic stability and ecological sustainability and considering potential effects and policy implications for many different stakeholders.
The Hague Centre for Strategic Studies (HCSS) helps governments, non-governmental organizations and the private sector to understand the fast-changing environment and seeks to anticipate the challenges of the future with practical policy solutions and advice.
