NATO has many times the industrial capacity Russia has. Fater 3 years of war Russia has adapted to war production but if NATO decides to do the same Russia will be outclassed quickly.

These are war game scenarios, though, as in reality it is highly improbable that Russia would start a conflict with NATO because they know they cannot compete. This doesn't mean NATO should not keep its game up, of course.

Russia is already in a low level conflict with NATO even if it's just NATO countries supplying equipment to Ukraine and Russia trying to hack NATO politics.
