No one can predict the future, but when a scientist comes up with a valid theory his predictions around certain scientific results come true. It’s a way to prove your viewpoint is the correct one.
Oh well, with so many parameters it is difficult to even come up with predictable outcomes. My prediction would be: If Finland joins NATO, Russia will not invade. Kind of obvious, I know. But working backwards from that, if Ukraine had joined NATO, Vlad wouldn’t have invaded. So... why didn’t they? The answer appears to be: It’s complicated. Not so complicated any more, is it?
“… but when a scientist comes up with a valid theory his predictions around certain scientific results come true.”
It’s also a mistake to treat global affairs such as war the same as science.
You are welcome to have your opinions, be they right or wrong, but to have the attitude that they are in some way related to scientific theory is hubris.
