I think it’s the other way around: Russia is aggressive but a show of strength would deter it. In other words, Russia isn’t desperate to avoid a confrontation with the West. Russia wants a confrontation with the West, and it needs to know that that’s a confrontation it won’t win. (China also needs to know that, and it’s watching the situation in Ukraine closely.)
That’s not to say that we should seek out such a confrontation with the goal of intimidating Russia. A high-stakes situation like that does have the risk of escalating out of control. However, the situation in Ukraine is already such a confrontation, initiated by Russia due to its belief that the West is weak. It would have been much better to avoid creating such a belief, but now is too late for that. The best we can do is to avoid reinforcing it and, from a pragmatic perspective, it helps that most of the risk is borne by Ukraine.
In short, the nightmare scenario is Russia invading a NATO country like one of the Baltic states. Then either there is a war between nuclear powers immediately or Western unity collapses and a war between nuclear powers becomes much more likely in the near future. Our best chance of avoiding that is to stop Russia in Ukraine, where we can do so indirectly.
Edit: Also people shouldn’t be down-voting you. You’re making a valid point that needs to be addressed.
