Re: Nothing New
"Oranges grown in the south are sweet, in the north sour" is an old Chinese reference to nations and supposed differences between them. The most interesting version of the story is all about counting diplomatic coup. So posturing has precedent, yes.
But... the pessimist can imagine four coming developments following from reasonable security worries.
One is that any business or industry that is credibly critical national infrastructure will be required to show not only disaster recovery style duplication of internal infrastructure, but also that one leg of that duplication employs only 'trustworthy' components. Think banks, local governments, energy companies, and the like.
Second is that it might become hard to find everything needed from unassailable sources. And so each state may find it necessary to sponsor and support domestic component development. Quite like China has been doing for the last few decades. Or, hey, like the fallout we've seen lately regarding GPS?
And this might be hard for hardware/software development, since the personnel devoted must also be unassailable (not on visa for instance). And so not only will governments keep winding the STEM, but make it more urgent through national service. "The Marine Corps builds coders!"
And then we'd come full circle. Would a company $here hire someone who has been in national service $there? Y'kno, weaponized?
A pessimist's thoughts are nightmares. I'm not suggesting the above, but am at a loss against the natural progression of ideas. What do you do to guarantee a nation's (or union's) security in the face of a hostile untrustworthy world?
