It reminds me.. when someone is cheating on a partner, they are more likely to think they are being cheated on too. I have experienced this, being accused non-stop when actually they were the one cheating all along.
Just because USA likes tampering with proprietary code and using NDA’s with Silicon Valley to bug just about anything they want (because they can), that paranoia consumes them that other countries are doing the same.
During times of war, other countries absolutely do the same.
Just looks at the western reactions about 'foreign agents' bill in Georgia.
But obviously an existential crisis is not the time that many governments stand on their principles, which is why 'war powers' tend to be justified under extenuating circumstances when countries end up at war.
There is no question, if there is another major war between world powers, they will invoke the authority to compel their industries to cooperate with the effort. If they don't, they'll quickly cease to exist.
