Whoops.. My bad.. Even still, its way more than enough was my point
It's never enough.
As for the original topic, the troubling part of this weapon being dismantled is that our entire nuclear arsenal is aging, and there are no replacement weapons being developed. That means at some point we will be forced to give up one or more of our nuclear triad deterrent forces, and it would be a minimum of 10 years before a "crash" development program could revive it. There is already a gap developing, due to some systems being within their obsolescence window and funding being shut off from the replacement/refurbishment programs.
We knew this would happen approximately 4 years ago, because we were told it would become national policy to stop nuke weapon development. The capability gap is probably unavoidable now. Once you give up nukes, even if development is merely halted for a couple of years, it's hella-expensive to get them back.
