Thank you for your thoughts and solidarity, but I can neither agree nor hope for a military intervention. Although I do have a few escape plans handy, and count myself a military buff, I do not wish to have to play ironman This War of Mine in real life nor wish it upon anyone. I may be somewhat fortunate in that I have plans to live elsewhere even before the current crisis, but I have friends who do not have the means to leave the city in a sudden, nor the means to sustain a livelihood elsewhere. I'd be damned to see them stuck in a war-torn hellhole.
Risking a bit to say this, although it may be emotionally satisfying to decisively, spectacularly punish China for its human rights abuses and oppression, doing so via military force is quite possibly the worst way to do so, especially when you think of the human costs involved. That said, I do wish the UK never left. Things would have been better if HK stayed a colony, or even joined the Commonwealth.
From a realpolitik perspective, it is difficult to see what the western world would gain trying to militarily intervene in the situation here. Although China is pretty much the enemy in a new cold war, there are already enough western aligned countries around China to surround it, e.g. Japan, RoC, RoK, and a bit further out, Australia and New Zealand. HK is not that important as a foothold. This is not counting the general war-weariness in the west post-War on Terror.
As for me, my hopes are to get out and start again elsewhere, and try to see to the people important to me being safe.
