I am hearing this since mid 2000's, War in Afghanistan will never end because US is stuck to be honest, if they leave, Taliban will take over and it will be a official US defeat, and US can not have it as a Super Power it will be embarrassing for them, if they stay they have pour in money and lives of US citizens in a senseless and endless war, US has a huge ego problem which is understandable for them because they are Super Power, but war in Afghanistan has no end in sight specially how Americans are collaborating with India and not people who can actually make a difference on ground hint ( Islamabad ) .
