Likelihood of a Limited Tactical Nuclear Exchange

We have recently heard some discouraging reports about nuclear capabilities and potential conflicts.

Like the report that Israel has nuclear weapons trained on Iran.

And, if you read today's posting(s) in our sister publication, The Anti-Zen Handbook, that US troops are being pulled out of Iraq and moved to a new Asian location, also a recent nuclear power.

Is the real reason for the "surge" in troop deployment as described by our current administration? To replace US troops being secretly moved and deployed to another nuclear nation - a rogue nuclear nation? Is a limited nuclear weapons exchange - or another war - now imminent?
