Barack Obama is now making his move by calling for a nuclear free world. Obama proposes that the United States enter into discussions to ban all nuclear weapons and prevent others from acquiring them.
It sounds nice, but the nuclear genie is long since out of the bottle. Hence, total disarmament is impossible and considering the nasties out there, I think undesirable. But what might be achievable is to a post-Cold War system of all the nuclear powers (the US, UK, France, Russia, China, India, Pakistan and Israel) to limit total yields, with a verification mechanism (trust but verify are great words to live by).
If Obama wants to do propose something to make people take notice, an idea would be to propose decommissioning the remaining 300 US warheads in Europe. But as I am a Republican, I doubt he will take my advice.
Could we be seeing President Obama?
While Clinton is ahead comfortably in the national polls, the polls in Iowa show a close race between Obama, Clinton and John Edwards. The Iowa caucus is very early this year. Furthermore, as a caucus, depth of support is just as important as breath -- it does not matter if 90% of the people want Clinton if the 10% that wants Obama are the only people willing to show up and stand around a gym on a cold January night. Obama has shown that he excites people, so that may be the advantage for him.
