I would like to repeat the following:
They are killing HK themselves. HK belongs China. HK has 7 million vs 1.4 billion.But SG should not don't gloat at HK's current Sep 2019 troubles. Eventually China will sort out HK's 2019 violent riot problems. The mob inciters/foreign powers' subversive agents will be rooted out. HK violent rioters will have rehabilitation/re-education jail time to adjust them to behave in a civilised society upon their release. Looking at the long term - a renewed & revitalised HK is in far more advantageous circumstances than Singapore. Just think of Singapore's water issues after 2061. That is an existential issue. And that is only 1 out of many problems Singapore has to face. When Prabowo becomes the next president of Indonesia and a new UMNO Version 2 + PAS gets elected into power in Malaysia GE15; Singapore has to face a sensitive and potentially dangerous situation. In all these aspects, HK is far more fortunate than Singapore.
