Such catastrophe can result accidentally from electronic failures or glitches in warning systems and from the recklessly aggressive and unnecessary force buildup against Russia. Conn Hallinan discusses these issues. http://fpif.org/may-greater-risk-nuclear-catastrophe-cold-war/

I doubt Hallinan is correct about Washington's military predominance. This is Washington's view, and this view makes Washington confident that it holds the aces. It is a mistake for Hallinan to encourage Washington in this view. Nevertheless, Hallinan makes it clear that we could all be vaporized at any minute. This extremely high risk has been created entirely by the Clinton, George W. Bush, and Obama regimes in which zionist neoconservatives have controlled foreign and military policies.

It is tiresome to hear the argument that nuclear war won't happen because it makes no sense. William Perry points out that the failure of a 49-cent computer chip resulted in NORAD's computers signaling that the Soviets had launched 220 nuclear missiles at the United States. Just think about all the failures and glitches in our own personal computers, even the best ones.
