Hong Kong media tycoon Jimmy Lai ordered back to jail

the UK should at least take back control of HK Island and the Kowloon Peninsula, these were territories ceded to Britain in perpetuity, and China only got them (together with the return of the New Territory) because of the Joint Declaration which must be maintained until 2047.

The UK has no means to accomplish this. Even the US and UK working together probably could not do it, and there would be incinerated cities all around for trying. Stick to ideas that can be realistically implemented. A 100% trade and travel embargo would do grave damage to China and would not result in the losses expected from a war over Hong Kong. Do your part by boycotting Chinese products at every opportunity.

Voicing certain opinions can now carry up to a lifetime prison sentence.

That doesn't seem good for poltical discusssions or freedom.

The UK looks very weak in light of the blatant mistreatment by China of the Joint Declaration, the UK should at least take back control of HK Island and the Kowloon Peninsula, these were territories ceded to Britain in perpetuity, and China only got them (together with the return of the New Territory) because of the Joint Declaration which must be maintained until 2047.

On another front, China gas now arrested nuns from a Kowloon Catholic mission as well.

These thugs will stop at nothing, it's time China is given the binary treatment by the global community, good or evil (China).
