I think this is one of those things that sucks but may be necessary.

You need to trust the knowledge workers that make up your economy to not send your research to a hostile nation so they can take advantage of your R&D investments.

And you need to know that your critical infrastructure (beyond Internet and trains, think about electricity and running water) isn't vulnerable to being slowly pwned and then shut down all at once in a catastrophic event that coincides with a forcible military reunification of one Asian country with another.

Although the latter problem is less malice and more general incompetence in the cyber security realm. Can't solve that with a security clearance or RTO. Solar Winds anyone?
