These weapons need to be ready to retaliate with few minutes of advance in case of a first strike and Russia is engaging in an active war directly on it's border. Additionally, they are fully aware they are provoking nuclear powers right now and Bombers have been patrolling in neighboring countries since the war started. If they haven't been in alert until now, I don't know what Russia is doing. Obviously I'm not an expert, but this looks like a symbolic gesture at best.
