The Chinese nuclear weapons program and missile program were both helped greatly when Qian Xuesen[1], one of the co-founder of the Jet Propulsion Laboratory, returned to China during the Red Scare in the 1950s.
Already incredibly wealthy (if you think inequality is bad in the US, you should see Shanghai or other parts of China) and had no intentions of staying in the US and were just here for education. It was extremely common to see Chinese students driving around in BMWs, Mercedes, Audis, and very often nicer cars, and it became something of a stereotype with most of the people I knew. Not to mention my university was taxpayer funded.

Mobility problems are mostly for Americans, not for ex-pats.
Geopolitics is a little important, but for most people, it's about their job, their opportunity.
It's troublesome because 99% of US companies and Chinese ex-pats just want to do work and are getting caught up in geopolitics.
But to be fair: this is a real problem. Espionage, influence, interference is a thing. Here in Canada, the Chinese gov. is directly influential in student activities etc. - at Ryerson in Toronto, a young Tibetan woman was elected head of the student union and it met with fierce and organized resistance from Chinese students, supported by tentacles of the state. As a small example.
That said it'd be nice if there were better ways past this problem, because it's not a problem for most of us!

A bit of a decline but "decimated" is too strong a word for a decline from 385,000 to 324,600, and much of that is due to smartphones and tablets (and single-board computers like the Raspberry Pi) that reduced the need for custom electronics. For example: in the 90s I worked for a company that made a custom handheld device. Now that product is an app.

What better instrument than a graduate student?
Sure, we want to be open and inclusive to everyone, but don't be stupid. Don't let the country that literally partners up with North Korea (https://en.wikipedia.org/wiki/China%E2%80%93North_Korea_rela...) and have hacked and infiltrated other countries before have open access to cutting edge technology.
During university, I've heard from a chinese student (From China), who's dad owned a high tech factory. He told me the plan was to get a job at the most reputable tech firm in that industry, and learn from it, then bring it back to his dad.
Those scientists moved to the States, which was America's gain and Germany's loss when lots of Weapons Research happened during the forties.
America seems determined to lose out when Chinese scientists are barred from US jobs, or when Chinese space engineers are refused any interaction with NASA.
Two most of these people are students and there a huge line for students to come into US universities. Unless china has a another plan to invest heavily in western free and democratic schooling they won't lose that edge.
Long ago I worked in defense and had some export controlled hardware (unlocked/no restriction high performance GPS and satellite technology)
What it meant was that to work on our stuff you had to be a "US Person" and "export" could be a conversation with the wrong person. In practice it meant the work couldn't be shared with students from a short list of countries. The punishment for infractions could be as little as recording and notification and as severe as significant prison terms. "Export" happens quite a lot and usually consists of innocuous mistakes.
I can't see Intel or Applied Materials or even UPS having Chinese H1-Bs around in the future. While there are some here who wouldn't mind having a Chinese Exclusion Act in their industry, I'm hopeful a majority of voices here will see the problem inherent with moves like this.
I count military and control of the international monetary system. That isn't a winning hand unless the Chinese shoot themselves in the foot with corruption or a return to their communist roots.
Also, I have a bit of ill will toward US universities that turns down US students in favor of Chinese students. I'm looking at you, UCSD.

Not all high-performing students will do well regardless of their environment. Some will crash and burn without support, and that doesn't only mean "accelerating them farther faster". It can be enough to group them together with other kids that are similarly enthusiastic and curious, so that they don't shoot each other down.
