If Zelensky wants a preemptive attack on Russia he has the manpower and aircraft to launch all the preemptive attacks on them he wants considering the Russian border is only a few miles from his current front lines. He's gotten more than enough arms delivered to counter attack Russian territory any time he wishes.
The U.S. and the NATO alliance is not running any dogs in that slavic fecesshow that should require any more support than supply defensive arms for the smaller country invaded by their larger neighbor.
I’d we are going to do that we will need to hit China as well,besides Russia and Former Soviet sites.
