Falkland Islands, pop 3,600 [0] - can they sustain a "behind the scenes"?
The Chinese National People's Congress is around 3,000 members. A bit of net emigration and the Falklands would be smaller than a legislative body.
It isn't really possible to fight the community on an island that small. If a lynch mob forms it could potentially include the entire 10 people in the police force and nobody saw nuttin'. Corrupt, but overt.
That's not really a great example; the reason 人民代表大会 can be so big is that the legislative decisions it formalizes are mostly made elsewhere.
The national emergency seems to be that they want to do something that is explicitly illegal. The article seems to be missing important context on why they expect to be able to do what they are doing.
