Self-fulfilling prophecy

I am very worried by the easy dismissal of the possibility of eliminating nuclear weapons. I don't see this as realism but as defeatism.

I think that members of the class underestimate the potential power of the international community if and when it can become unified behind the goal of eliminating weapons. I also believe that the extent to which the U.S. as been an obstacle to positive change and, accordingly, the importance of the change in the U.S. position is being underestimated in this class.

If the global community cannot come together on issues such as the elimination of nuclear weapons and confronting global warming, we are, frankly, doomed. Are you really willing to accept this fate? Don't you think that accepting it as inevitable makes it more likely to come to be?
