No, the worst thing for European security would be to not have enough military strength to stop Putin if he decides he wants Poland (as prominent Russians have said they should take, after Ukraine). And then East Germany, and Chechia, and Slovakia, and Hungary. And then who knows if he would decide he is done? Not being able to defend yourself is strictly worse for security than being able to defend yourself. I don't know how you can think otherwise.
