There should never be nuclear posturing threats by any nation and their military. Countries that have nuclear capabilities are now knowledgeable of missile movements from intelligence gathered from cyber-space etc. All sensible and responsible major powers should in fact be wary of intentional or "accidental" nuclear missile launches by rogue states and terrorist inspired countries; especially their use of black-mails against any country. Major nuclear powers like US, Russia and China know the consequences of any nuclear war where no one wins, and results will be devastations to cities and innocent citizens. Peace is important for all people (present and future generations). The alternative is unimaginable. Let the OWLS (Diplomats) continue to advise and inspire the major nations' leaders, and never allow the HAWKS to gain the upper hand. Difficult BUT possible thru' pragmatic meetings & "Thinking Heart" negotiations.
