The London Guardian opines,
An elite team of officers advising the US commander, General David Petraeus, in Baghdad has concluded that they have six months to win the war in Iraq - or face a Vietnam-style collapse in political and public support that could force the military into a hasty retreat.

Possibly the biggest longer term concern of Gen Petraeus's team is that political will in Washington may collapse just as the military is on the point of making a counter-insurgency breakthrough. According to a senior administration official, speaking this week, this is precisely what happened in the final year of the Vietnam war. Steven Simon, the national security council's senior director for transnational threats during the Clinton administration, said a final meltdown in political and public backing was likely if the new strategy was not seen to be working quickly.
