anti missile shield for singapore

This is the headline by a Defence Correspondence, David Boey, in the Straits Times today. The main point in the article is that it is prudent for Singapore to have anti missile shield now that it is within the range of ballistic missiles from North Korea, China, Russia and the USA. Now let me see, does any of these nations has a reason to shoot missiles at us? North Korea does not even know that we exist. China is our good friend and has publicly stated that it will not be the first to use nuclear weapons on any country. Presumably firing an ICBM and to be cost effective, it must have a nuclear warhead and not 20 kilo of TNT. Russia, well, think it will be too busy with Eastern Europe. The USA? Our closest allies, but could be a threat if they decided to leave us out in the cold when they found a more valuable friend. It has all the capabilities and has been threatening everyone they don't like with pre emptive nuclear threat. So shall we buy an anti missile shield from the US to defend against American missiles flying at us? And if they do so, I don't think any anti missile system can hold them back. What about the others, including potential new enemies from the Middle East? Now, why would we have enemies who would find us so naugthy of deserving a missile strike? Possible, if we keep perching on top of our HDB flat and show our two fingers to people we have nothing to do with or showing them monkey faces. I would think it is more prudent to take a low profile, be friends to everyone, and use the money to build a few more IRs. PS: In the case of Malaysia, by the time the missile is airborne it will be in Indonesia.
