Cowardice in general has become way too socially acceptable. Actually the norm. If you G-d forbid act so that you can be unambiguously determined as not a coward, then G-d help you.
And cowards understand each other very well. You can even expose them all as cowards, they’ll accept the shame and admit you’re right and all such, and then they’ll still feel victorious, because in a society of cowards cowardice always wins in all ways but one.
Living like “Hagakure” for real is perhaps the only way to preserve your humanity in some life situations, but that won’t lead to happiness. And the author of “Hagakure” refused to commit seppuku when his suzerain died, because “times have changed”.
And meeting people who live by those principles, you damn hard wish they hid or cowered or stepped back that one time that led them to pain for their remaining lives from those not worth their breath.
I’m thinking of a woman, by the way. Men of that quality are far more rare.
Older Soviet tanks play turret toss, you know why? Their automatic loading system is optimized for fire rates, but not safety. You know why that and what that achieves? That achieves a whole lot of tanks built during Soviet times for mass ground warfare in the WWIII as it was imagined then. When it’s one safer NATO tank against 5 worse but comparable (and fast-firing) Soviet tanks for the same expense, the choice (with Soviet doctrine) is obvious.
There was no brain drain then, these were all conscious design decisions making a difference of the scale of hundreds of tanks built.
Unfortunately no.
You are a few years late even in talking about tanks.
That’s also something most Russians have passively understood by now about modern warfare, it’s all about information, planning, coordination done by many small drones, with humans reduced to techs and operators and, of course, small assault groups. Tanks have no place in that.
Brain drain is something that was happening when plenty of Soviet-educated engineers and scientists simply had no place in ex-Soviet countries, or by any measure the offers they could get were far better in the West. Right now there’s no coordinated incentive for said brain drain from the western governments. Which was a thing then.
Right now - yes, I think oil money that buys western components for weapons can buy expertise in areas of interest.
