Something can be a problem without it making sense to worry about it. If Russia is using nukes, it becomes particularly absurd to continue to follow rules purported to appease them so they don't use nukes. At best it's a transparently nonsensical excuse that conceals some other motivation. When important people say they are against doing X, Y, or Z because of the risk of nuclear war, we can at least pretend they are serious as long as no nukes have been used yet. But is there any other motivation they could have? There's one that seems very obvious to me, especially when I saw the reaction to Lindsey Graham's comments about regime change.
