What's wrong with letting Japan defend itself? Or S Korea?
Nuclear proliferation was a false flag when Pakistan and India got nukes. Couple that with Bill Clinton giving nukes to N. Korea and now Obama OKing Iranian nukes.
The cat's out of the bag. What is needed now are strong alliances and the fortitude to defend those allies so that nuclear weapons are not used. That's simply not the case as the world stands now.
It’s not that simply. Good people, mostly military but some DOD’s, job is to study various scenarios and the worse thing that could happen is more nukes out there. Laugh it you want to, but more nukes is more for the bad guys.
