US President Barack Obama has removed Gen Stanley McChrystal as his top commander in Afghanistan over his highly critical remarks about senior administration officials, saying that he did not live up to the standards for a command-level officer. Making an announcement at the White House, Obama said McChrystal will be replaced by Gen David Petraeus who had successfully led the multi-national forces headed by the US in Iraq war. Petraeus currently is Commander of the US Central Command. Obama emphasised that this is a change in person and not a change in policy, as General Petraeus has been involved in the Afghan policy since the beginning of his administration. The US President said, the conduct represented in the recently published article carrying the remarks of McChrystal does not meet the standard that should be set by a commanding general. Afghan President Hamid Karzai's spokesman says, the Afghan leader respects US President Barack Obama's decision to replace the US and NATO commander in Afghanistan, General Stanley McChrystal. He says, the President Karzai looks forward to working with McChrystal's replacement, General David Petraeus.
