US to loosen nuclear weapons constraints and develop more 'usable' warheads

1. Cannot comment on the new posture....

As i can't read the article yet. But I will say the development of new weapons is an unfortunate necessity of being a nuclear power. Nuclear weapon design requires unique knowledge and skills and not developing new designs risks a "brain drain" where people with the necessary skills either die off or retire without passing useful knowledge on. Unfortunately, as long as the rest of the nuclear powers modernize and develop new weapons, we must as well to maintain our technological leads and parities.
