Yesterday I read in 'Der Spiegel' that the speech of Obama related to the war in Afghanistan was not that convincing. There is not really a good reason for the war.
It is probably for any economic or power increasing interests.
Well, only a certain percentage of the population will accept that while many will be against the war in face of such reasons. For that you need a lying propaganda about any ideals the US army would be going for in this war.
I have an idea. Obama should make a make an (open) contest to find such a reason for this war and offer people who bring about the best reason and strategy how to sell it to the public a reward in money. The money he could take from that he won with the Nobel Peace Price, if he hasn't given all to charities.
