@gone for good
The picture I've posted here is just an illustration of what actually poses a real threat - a government propaganda of hatred towards other nations, countries, and even civilizations.
And no, I don't believe countries should not have armies and some kind of army ads (at least not in the world we live in now) - but what's happening in Russia and the territories under Russian occupation (like Crimea) is far beyond what is normal. I know what I'm talking about (and you can google it if you'd like to). Military trainings/events at kindergarten/primary school is not a standalone practice - it's just a small part of the whole modern-day Russia's war-mongering, hate-possessed culture, society, media, etc. So, there's great chance (I'd say 100%) that some of those children will become murderers, and terrorists (optionally wearing army uniform).
JW indoctrination/harsh practices can definitely trigger/worsen some mentally illness - but it's next to nothing when compared to what Russian gov't/media purposely do to kids' minds.
