Your brain isn’t what “collapses the wave function”, it’s the measuring device that you use. You can do a double slit experiment and watch it with your eyes the whole time. Light will still act as a wave until you interact with it experimentally.
You are reading too much Deepak Chopra. Your brain is just a computer made out of meat. It’s not magic.
This was done on purpose so the crisis didn’t escalate. There’s no world police to prevent Russia from nuking everyone. It’s better for outside actors to focus on de-escalation anyway.
Also, Putin is not doing this because of Ukraine. I mean that’s part of it, but he is doing it for domestic appeal. He wants to appear tough to Russian citizens. Two situations allow that: beating Ukraine easily, and losing to NATO forces. He knows NATO will not risk invading Russia, so he’s in no real danger from the second one.
NATO is intentionally not intervening because it makes Putin look weak domestically. Russia has created their own problem and the war will not end until the people of Russia demand it.
