The consequences of a "small" nuclear war would be widespread and long-lasting.

Regional nuclear war would have worldwide fallout

If you think a small-scale nuclear war between, say, India and Pakistan would only devastate part of the Asian subcontinent, think again. A new report suggests that the effects of a regional nuclear exchange would have global environmental impact. What can world leaders do?

"Our research supports that there would be worldwide destruction," said University of Colorado at Boulder Michael Mills, co-author of the study and a research scientist at the University of Colorado at Boulder. "It demonstrates that a small-scale regional conflict is capable of triggering larger ozone losses globally than the ones that were previously predicted for a full-scale nuclear war."

Combined with the climatic impact of a regional nuclear war -- which could reduce crop yields and starve hundreds of millions -- Mills' modeling shows that the entire globe would feel the repercussions of a hundred nuclear detonations, a small fraction of just the U.S. stockpile.

What should the United States do about nuclear proliferation? Do such studies lend new urgency to efforts aimed at disarming Iran and North Korea? Is nuclear deterrence still viable? Can nuclear war be averted in an age of terrorism?

Ben likes: By the shadow of our hand

Wretchard/Belmont Club

The Guardian describes an extraordinary manifesto authored "by five of the west's most senior military officers and strategists..." At first glance, the manifesto appears to mark a return to the policy of deterrence; a rueful admission that nothing but a revival of the balance of terror can now secure the West against forces that its publics are unwilling to mobilize against. That thought will ironically comfort many of those who lived through the long shadow of East versus West. After all, if deterrence kept the West safe against the Soviets for the long duration of the Cold War might not containment and the mutual balance of terror also safeguard it indefinitely against radical Islam?

Deterrence worked because it made peace the only alternative to utter destruction. But it worked against the Soviets because for all their belligerence could always be counted on to choose life. The Commissars may have been stupid but they were not crazy. Can the same assumption be made about Islamic radicals who desire death? From the point of a theocratic zealot the rational choice may be to hasten Armageddon.

On closer inspection the manifesto might not be about deterrence at all. It is about committing to prevent terrorists from acquiring WMDs at all costs. The reason Lord Inge's remark that "to tie our hands on first use or no first use removes a huge plank of deterrence" is so significant is that it brings the trigger point back from second-strike or launch on attack to one in which WMD acquisition itself becomes the casus belli. It is almost a form of pre-deterrence.

Joel likes: The greatest ecological threat of all

Tomdispatch interview with Jonathan Schell

You know, when I wrote The Fate of the Earth, back in 1982, I said that, first and foremost, nuclear weapons were an ecological danger. It wasn't that our species could be directly wiped out by nuclear war down to the last person. That would only happen through the destruction of the underpinnings of life, through nuclear winter, radiation, ozone loss. There has been an oddity of timing, because when the nuclear weapon was invented, people didn't even use the word "environment" or "ecosphere." The environmental movement was born later.

So, in a certain sense, the greatest -- or certainly the most urgent -- ecological threat of them all was born before the context in which you could understand it. The present larger ecological crisis is that context. In other words, global warming and nuclear war are two different ways that humanity, having grown powerful through science, through production, through population growth, threatens to undo the natural underpinnings of human, and all other, life. In a certain way, I think we may be in a better position today, because of global warming, to grasp the real import of nuclear danger.
