The award of 2009 Nobel peace prize to Barack Obama is a new experiment. It is like advance payment for goods to be delivered.
A science Nobel prize opens up the field for future Nobel prizes. But peace is a goal. If all the Nobel peace prize winners in the past 100 years had actually deserved it , the prize itself should have become redundant by now.
Obama is the best thing that has happened to US and the world at large in a long time.For the sake of humankind one hopes he would succeed.
But at the moment the Nobel peace prize for President Barack Obama looks more like an honorary doctorate.
