yea i’ve had people be like ‘we can hit them with nukes from anywhere why does ukraine matter’ but like having 20 or 30 minutes to detect an incoming ICBM from the ocean (to maybe shoot it down/knock it off course or get everyone into bunkers to launch your own counterattack) is a much better situation in terms of deterrence than having 5 minutes to maybe detect a launch from concealed/rough terrain and have just enough time to let everyone in the nuclear command center/capital city know they are going to die (missile nerds correct me if i’m oversimplifying, ICBMs at long range need to reach near-orbit heights in their flights whereas closer range missiles can be launched to fly somewhat closer to the ground in ways harder to detect with radar or intercept with missiles of your own)
