The vulnerability of Singapore was deeply felt, with threats from multiple sources including the communists, Indonesia (with its Confrontation stance), and UMNO extremists who wanted to force Singapore back into Malaysia. As Singapore gained admission to the United Nations, Lee quickly sought international recognition of Singapore's independence. He declared a policy of neutrality and non-alignment, following Switzerland's model. At the same time, he asked Goh Keng Swee to build up the Singapore Armed Forces (SAF) and requested help from other countries for advice, training and facilities.
