FIRE people: Russia likely to attack Europe within 5 years: what do you do?

After reading this article: https://www.7sur7.be/monde/la-russie-va-t-elle-cibler-d-autres-pays-apres-lukraine-un-expert-met-en-garde-leurope-en-sommeil~acd2f3b0/?referrer=https%3A%2F%2Fwww.google.fr%2F

I'm seriously afraid. I invest in stock ETFs and in real estate in Belgium and my goal is retiring early. But if what this expert says actually happens, all these decades of investments will be worth peanuts. Not to mention that living in Europe will be a nightmare. I know that many will reply that it's BS, that I should ignore this, that it's unlikely, that it's only one guy, that it's the "mainstream media", that if it happens, the whole world will be impacted (not true btw) and all the usual denial that I'm tired of hearing. I'd like to read sensible replies, actually considering this very possible risk. What do you do to apprehend that enormous risk, to protect from it? It's a genuine question. I hope that this post won't be removed and that answers will be truly informative. Thanks
