All great to have first strike capability but irrelevant given the size of Malaysia or Indonesia. Just think about it will us 30 mins to hit KL - so they have a 30 min head start. They can reach almost anywhere in Singapore with 155 howitzers (low tech) placed in the plantations
On the other hand, even without superior weaponary, it does not take much for Malaysia to takeout out power plants, water purification, incinerators, sewerage treatment plants. Even airport runways can be easily taken out.
Jurong Island can easily be set ablazed.
Once the water, power supply and sewerage treatment is gone, office buildings with their fixed glass curtains are too hot to work in. Lack of potable water and rotten trash will be a health hazard. Remember that Singapore is a very densely pop city set in a hot humid tropical weather.
Unlike Kuwait we have no oil to come back to. Our assets (port faciltities, cranes, MRT, bridges) can easily be destroyed (kind of hard to destroy oil reserves 2000 ft underground). Our attraction as a safe place to invest and live is gone. Overnight the ang mor suddenly realize that we are just a few miles from largest muslim pop in the world.
And should our neighbors remain restive, even the shipping business is gone. Any idiot with an RPG can make ship vulnerable along Straits of Malacca.
What we will have is a bunch of rich gov officials living overseas. All that weapnary placed overseas is useless. How are you going to bring it back and place it against the enemy. In US invasion of Iraq, US used Kuwait as Saudi/Kuwait as staging area. i doubt if Thailand will offer the same
