High Quality Content by WIKIPEDIA articles! Total Defence (or TD) is the name of Singapore`s comprehensive defence strategy, adapted from countries like Denmark, Sweden, Switzerland and Austria. It is based on the understanding that besides military action, aggressors can also defeat the country by wrecking its economic systems, tearing its social fabric apart, targeting Singaporeans` beliefs and commitment to defence, and its ability to recover from disasters, both natural and man-made. The Total Defence concept encompasses five key aspects – military, civil, economic, social and psychological defence – and focuses on the need for each Singaporean to play his or her part to defend the nation.
