Barack Obama's war: the final push in Afghanistan

Barack Obama is to set an ambitious timetable for the withdrawal of US forces from Afghanistan, with the first troops pulling out by July 2011. The announcement is aimed at countering US public fears that the country is being sucked into a Vietnam-style morass.

Reflecting the increased sense of urgency, Obama is to speed deployment of an extra 30,000 American troops to Afghanistan within the next six months a much faster timetable than the 12 to 18 months that had been briefed by US officials up until today.

The 30,000 figure is lower than requested by the US commander in Afghanistan, General Stanley McChrystal, but the Obama administration is hoping that other Nato countries will make up the difference.
