Guest columnists

In conceiving the idea of a Guest Columnist section we are motivated by the urgent need to find lasting solutions to the various threats to global security by relying on expertise, experience and innovations of persons, institutions and organisations we can aptly regard as custodians of global security – those persons, institutions and organisations that are actively involved in security matters and contending for the liberty of mankind.

Among such include security experts, security advisers, managing directors/chief executive officers of security companies/institutions, intelligence experts, service chiefs, security chiefs, ministers in charge of security in their various countries, secretaries of state, UN Security Council chiefs, heads of UN Peace Keeping Force around the world, NATO chiefs, serving or retired, heads of governments/ex-heads of governments, diplomats and international civil servants with responsibilities for security in and around the world, academics, researchers, etc.

To these categories of persons and representatives of security institutions and organisations throughout the world, we invite you to be our Guest Columnists. Alongside your articles, we would like you to send us your bio data and a passport sized photograph.
