McChrystal recently submitted an assessment of the war in Afghanistan in which he warned of the danger of failure in the absence of sufficient troops. President Obama, however, stated he would ensure that he has the right strategy before committing to sending more troops. More than 30,000 extra US troops have been sent to Afghanistan since May this year, doubling the US contingent in the country.In Washington there have been signs of a widening gulf between US military commanders on the one hand - and senior political advisors to President Obama on the other.Although Gen McChrystal has not yet officially sent a request for more troops, his assessment makes clear that the Obama administration will soon receive one. Reports suggest that McChrystal might ask for an extra 40,000 troops. He is being backed by his superiors in the Pentagon.But in the White House there is still a debate about the military strategy. Those close to the President have cautioned against expanding the military operation. However, Gen McChrystal is hoping to diffuse the tension, saying in an interview with the New York Times that ‘a policy debate is warranted.’He also dismissed reports that he was considering to resign from his job. He claimed that success in Afghanistan is achievable, adding that he has not been limited in identifying additional resources that might be required.
