A world without nuclear weapons?

I doubt that the major powers will tolerate countries like North Korea having both nuclear weapons and rockets capable of being used as ICBMs. There was talk of shooting down North Korea's rocket that may or may not have put a satellite into orbit. http://www.guardian.co.uk/world/2009/apr/05/north-korea-rocket-launch

So this seems like a good sign for the future of space travel:

"Obama, who is making his debut on the world stage, said in
Strasbourg, France on Friday that he would lay out an agenda to
secure the world's loose nuclear materials and halt the spread of
illicit weapons.

He added that he wanted to offer an agenda "to seek the goal of a
world without nuclear weapons."
