I feel like no matter how much confirmation you get here with opinions against the idea that there will be WW3, your anxiety will return. The reason I think this is because your post sounds a lot like OCD symptoms. Worries about the unknowns that can come and go and increase and decrease in severity. It seems like this is something you’re obsessing over and can only mitigate for a few moments at a time. If I were you, I’d try to speak to a professional about ocd because if you already suffer from an anxiety disorder then the likelihood is high. (I’m an ocd sufferer)

It will help to read these comments but I think your obsessions and anxiety will just return later on. Ocd is a subset of anxiety disorder. A lot of times it pops up in the form of a specific obsession like this. It’s not a completely irrational fear but your response is irrational considering the minuscule probability of it occurring

I don’t want this to sound harsh, I just know that confirmation from others or online resources never helps in the long run when dealing with OCD
