What's your basis of this pretty strong statement that MSS is "extremely elementary if not downright useless" and do you have any evidence of their extreme incompetence. I mean, Hillary Clinton during her tenure as SOS wrote in her book with great annoyance hoe effective the electronic signal intelligence of China that she had to literally turn off anything and everything she had under the sun for fear that Chinese intelligence would gather relevant information without much effort. If that's a sign of China's intelligence being "elementary and downright useless" then American led intelligence and its vassals are even more incompetent and pathetic that despite China's shitty and useless intelligence the best they could do against their now avowed strategic enemy is to cause the Hong Kong riot, accused the country of genocide against "WEGERS" which are lame since it left China able to hold strategic chokehold on 15 out of 30 important strategic minerals, allow the country to become the defacto trade and manufacturing behemoth in the world; gained standing in research standing, leads in many critical technologies according to ASPI (another warmongering western pravda) I could go on.Yeah, I would say China's intelligence services is extremely elementary if not downright useless. They were totally caught off guard with the simmering HK protests which we now know had been organized and brewing for months.
And HK is not even some far distant land.. it's literally part of China!
I am surprised to read something so pedestrian and bereft of actual analysis from you since I thought you're one of the more astute and knowledgeable poster on this forum.
