GMS simply recounted what he saw. Many people have already seen UFOs. The air forces of all the major nations have also recorded similar encounters. Some of America's technological advances came from non-terrestrial sources. It's an open secret. But there's a huge conspiracy by the powers that be to keep the topic under wraps from the citizens. So everyone in power – the military, intel agencies, political rulers – buat bodoh and keeps mum.
Difference is that in the West politicians are free to say what they believe in. In conservative Singapore politicians can't do that. Say you believe in UFOs, gay rights or socialism and you're branded a looney, a dangerous madman or a self-radicalized extremist.
GMS's problem isn't UFOs. It's his ego and grudge against WP clouding his judgement at times. Personally I like his straight-shooting style. And he's got loads more courage than many of the keyboard warriors here who ridicule every word he utters.
