Prima facie, it appears scandalous as a plan calling for the "partition" of Afghanistan, but in actuality it is something else. In short, US forces should vacate the Taliban's historic strongholds in the Pashtun south and east and should relocate to the northern, central and western regions inhabited by non-Pashtun tribes.
The US would be extricating itself from fighting and bloodshed, while at the same time perpetuating its military presence in the region to provide a security guarantee to the weak Kabul government and as a bulwark against anarchy and extremism - on the pattern in Iraq.
The US's and NATO's profile as real-time providers of regional security and stability can only boost their influence in Central Asian capitals.
Translation: should this move forward, the US and NATO are never leaving Afghanistan; just as happened in Iraq, the war will be "rebranded."
