Bush and Obama administrations violated 1970 Nuclear Non-Proliferation Treaty (NPT) provisions. The ABM and Comprehensive Test Ban Treaties are ignored. So are the Biological and Toxic Weapons Convention and Fissile Material Cutoff Treaty. It prohibits additions to current stockpiles.
In 2010, the Obama administration's Nuclear Posture Review (NPR) reiterated earlier policy. It's old wine in new bottles. It remains in force.
It says America "reserves the right" to use nuclear weapons "that may be warranted by the evolution and proliferation of the biological weapons threat and US capacities to counter that threat."
The 2005 Doctrine for Joint Nuclear Operations remains unchanged. Offensive and defensive deterrents aren't distinguished. It says:
"The new triad (land and sea-based strategic bombers, land-based missiles, and ballistic missile submarines) offers a mix of strategic offensive and defensive capabilities, active and passive defenses, and a robust research development, and industrial infrastructure to develop, build, and maintain offensive forces and defensive systems....it provides additional military options."
Current Obama policy leaves land/sea/air triad deterrents unchanged. They're on high alert. Nuclear missiles can be launched preemptively.
So can bunker busters with conventional or nuclear capability. The so-called Mother of All Bombs "massive ordnance penetrator (MOP)" is designed to penetrate up to 200 feet of reinforced concrete. It does so before detonating an enormous explosive blast.
These type weapons threaten humanity. Enough of them can cause nuclear winter. Doing so would block out sun for years. Life on earth would end. The possibility is real. It's chilling.
