If you're gonna go pro-colonialist might makes right, that's your prerogative, but then you're just gonna have to eat it on the fact that the PRC had a lot more might nearby.
Do you think we are happier now that we have been "handed back to the motherland" or is China happy? Why does the opinion and desires of Hong Kong citizens not mater in your mind?
I don't want to devalue your experience, but Anglo powers have a terrible record of "colonialism for their own good", "we'll be greeted as liberators", etc.
