Contemplating on the security risks and threats of having too many foreigners

The full impact of having too many foreigners in a little island with only 3m citizens has yet to be felt by the owners of this island. But all the signs are there and more and more people are feeling the heat but could not do anything about it while the advocates of this policy continue to do as they pleased, to bring in more and more foreigners into a land scarce piece of rock.

I am wondering what would the people responsible for the security and safety and national interest of this island be thinking about this. Would they or have they done a risk analysis on this conscious policy to flood the island with so many foreigners?

The problems or consequences can be viewed from a few perspective.

1. How would so many foreigners affect the country as a whole, the citizens, and what level or percentage would be tolerable and manageable? The problem with this question is that it is complicated by the fact that foreigners could become instant citizens and counted as Singaporeans overnight, or be counted under the gray term called 'locals' and people may be misled to what they are, whether they are ducks or chicken.

2. The same questions can also be viewed at the level of a ministry, stats board, a GLC or corporation or company. What is tolerable, how many are tolerable, and what are the risks?

3. Going down the line, the risks and threats of having too many, how many foreigners, in a dept or section, unit of an organisation? Imagine the damage they could do, unhindered, unchecked, operating without being watched by Singaporeans, to the organisations and country?

4. What about their big presence, absolute majority or dominating majority in highly sensitive depts or units like finance, IT etc where they could cause untold damage and security concern if they turn bad?

5. What kind of security vetting and clearance are done on foreigners holding highly sensitive appointments in the country, ministries, stats boards, GLCs and corporations? Do they go through the same stringent security screening, and being a foreign import, how reliable are the vetting done on them and their backgrounds? There are many non govt corporations that should also require security screening and vetting.

6. Have the over representation of foreigners of untold backgrounds posed a security and safety risk to our country and national interest?

7. Is there anyone or organisation working on this, like the high powered Select Committee on fake news? Which of these poses a higher security and safety risk to the country?

Or is everyone and resources spent on witch hunting on lying academics or the opposition leaders? What are the real security and safety risks facing the nation and people that have been forgotten and letting wrong priorities set the agenda?
