Singapore’s defense strategy focuses on fostering deterrence and diplomacy. Deterrence is the fundamental strategy for Singapore’s survival and development, while diplomacy is a relationship-building strategy amid the stabilizing and balancing of the regional order that surrounds Singapore. These are the insurance prepared as firewalls to consolidate the national security capacity of Singapore. The decision-makers of Singapore fully understand that strengthening the armed forces may be seen as too provocative by its neighbors. Securing a country only through developing greater military power may have more consequences than benefits. Only by considering the establishment of harmonious relations with neighbors regarding security issues can the negative impact caused by upgrading military capacities be reduced. Hence, it is essential to address the necessity of deterrence and encourage enthusiasm for diplomacy so Singapore’s security strategy can be improved. With military power to shield the entire country as the first front and stable and supportive strategic partnerships with other countries, Singapore has built an unshakable security structure. This is the source of confidence and safety for its people.
