The fact a press release was made and random nobodies are speculating openly about a supposed act of war against China shows that it was anything but.Not exactly. Nothing is guaranteed at all. In any type of war, the enemy always gets a vote. It took an internal leak by Snowden, not Chinese MSS, or Russian FSB, to reveal how extensive the US spy network actually was. The Hong Kong fiaso was building up right under the CPC's nose, yet nothing was done about it. Success is never guaranteed.
Government isn't in the business of selling news stories with their intel. So of course it was Snowden, not China, that released the leaks.
Sponsoring traitors in HK was taking advantage of legal loopholes in HK itself. Even if the practice of using undeclared foreign agents to pay rioters and riot themselves is frowned on (yet it wasn't illegal until after the NSL), it isn't a clear cut act of war like an attack on China's military would be.
We should strive to be objective. Only fear mongers with ulterior motives think in terms of "enemies that are too strong and too weak at the same time". The enemy is dangerous in its own way, but it will not commit a brazen act of war that would be easily traced back to his homeland.
Fear mongering is stuff like believing the enemy is all powerful, hiding everywhere etc, it has never served any empire that implemented such thinking.
