The Pentagon's chief is undertaking the tricky task of convincing allies to remain committed to the war in Afghanistan even as the Obama administration continues to debate whether to send more troops to fight. U.S. Defense Secretary Robert Gates himself is undecided at least publicly on whether to order more forces to fight the Taliban in Afghanistan as his top commander there has requested or to focus more narrowly on al-Qaida terrorists believed to be hiding in Pakistan. Gates leaves Sunday on a weeklong mission to Japan, Korea and Slovakia in part to ask NATO partners and Asian allies for continued contributions to a war now in its ninth year. Perhaps mindful of asking others for help amid the U.S. indecision, Gates isn't only seeking military aid.
