Singapore's military doctrine is aimed primarily at our two largest neighbours, who are both our greatest friends and greatest potential threats. We aim to outnumber and outgun them, and taking a leaf from the Israeli doctrine, bring the fight to them instead of fighting at our borders. It's a huge step forward, as compared to our doctrine of the past of holding out for about a week, while begging US and UN to send military aid.
In this dog-eat-dog world, there are no permanent friends, only permanent interests. Always remember Henry Kissinger's advice before you keep yapping about cutting our military budget or reducing NS.
