So after the great Arab revolution comes the great Arab repression. The catalyst is the failure to support the Libyan uprising. If the USA can not only stand by and allow such an unambiguously evil act to take place, but also block others' frantic attempts to secure help, then dictators the world over can sleep soundly and let loose their security forces. We still don't know what the final outcome will be yet, though it seems clear that thousands of brave people who wished to live in dignity and freedom will die cruel deaths simply for wanting something that we take for granted.
This was a great historical opportunity, a chance for a momentous transformation of the Middle East. The failure to understand this, welcome it without reservation and then to take action to support it is a crime. Obama is not the first Nobel peace laureate to have blood on his hands.
