I really want to say yes to this, however, I've been a part of two wars and an active participant in one of those wars. As long as there are despots in the world, Russia (we will bury you) , China (we will wil buy you, then bury you), North Korea (we will destroy you), Iran & Pakistan (we will convert you or bury you), India (we ill overrun you and bury you), all of which are nuclear, there needs to be some sort of nuclear deterrent. We are that deterrent. Maybe someday, it hasn't happened in 5000 years, we'll all be able to play nicely on the planet. Unfortunately, that's not the case today.
