It was possible to predict the Ukraine war; such an operation requires planning, troop moves, etc. It's very clear US intelligence had a good handle on this.
Predicting the next war now prior to any such planning/moves is a silly expectation of people, even if they're experts.
If Russia starts moving troops towards Finland, and intelligence agencies start getting indications from electronic and human intelligence, and the rhetoric starts ramping up, you start being able to make more educated predictions.
