A diplomatic dance has commenced between the US and Afghanistan over a US request for legal immunity that would enable a contingent of American troops to stay on beyond 2014.

Failure to agree on an immunity deal in Iraq ensured that US forces pulled out completely by the end of 2011, further diminishing American influence there despite toppling Saddam Hussein in 2003 and fighting a bloody counterinsurgency to backstop the governments that followed. Now, observers are watching to see how Afghanistan will handle the issue, which would determine just how many soldiers stay past a 2014 deadline for withdrawal of combat troops.
