Hong Kong protestors are out on a limb

It seems China may be about to offer a more assertive response to the protests in Hong Kong. Prominent activists have been arrested in recent days and they join the 900 arrested since protests began in June.
That Chinese military vehicles have been moved into Hong Kong adds to the sense that some sort of an endgame is at hand or, at the very least, that Xi Jinping’s administration is running out of patience with its opponents in the former British colony.
