You dont think that Chinese espionage does not potentially extend to our colleges?Well, no, I'm not sure what "espionage" would mean here? Does it mean stealing information? Doubtful. Unionizing graduate students? Hard to believe. Thwarting the education of others? Haven't seen it. While the Chinese may be placing people into positions at American universities with the idea that they might one day be useful, I'm not sure what would could as espionage. If anything I'd guess the "operatives" would mostly be keeping track of the activities of other Chinese students, and possibly serving as conduits for more covert operatives, but I'm doubtful they are doing anything that would legally qualify as espionage.
You dont think the U.S. is doing at least as much elsewhere?
You'd have to be clearer about what the "as much" is, but I'm doubtful the US is putting much effort into putting operatives into academic positions abroad. Probably they want to open channels of communication with people who are already there, but I'm doubtful we're doing anything particularly effective involving "fake" students. And again, what would the goal of this be?
All this talk of collusion with Russia recently doesn't bother you
Seems worth investigating, but no, nothing I've heard so far bothers me. There are lots of countries that have great interest in affecting/effecting US policies, and I'd presume that Russia would be one of them. I'm doubtful they were particularly effective in influencing an election, though, or even that they were the country with the greatest influence. This is the place where I assume the US is doing much more with regard to other country's elections, possibly with greater impact.
Particularly in an authoritarian nation swarming with propaganda.
I don't know your politics well enough to know if you mean China, Russia, or the US here? If you point is that there likely exist Chinese students who are willing to do what the Chinese government asks them in return for being allowed to study abroad, then sure. But I'd guess that most of what is being asked is "Learn everything they will teach you and then come home and build a better China", and I think that's a good thing?
