At the NATO summit in Chicago, Obama refused to talk with Pakistani President Zardary:

The rift between the US and Pakistan deepened on Monday as the Nato summit in Chicago broke up without a deal on Afghanistan supply routes.

Barack Obama, at a press conference to wind up the summit, made no attempt to conceal his exasperation, issuing a pointed warning to Pakistan it was in its wider interest to work with the US to avoid being “consumed” by extremists.

Seldom in recent years have the tensions between Washington and Islamabad been on public show to the extent as at the Chicago, overshadowing the two-day Nato summit.

The main point of friction is Pakistan’s closure of Nato supply routes to Afghanistan in protest over drone attacks and a US air strike in November that killed two dozen Pakistani troops.

Obama refused to make time during the two-day summit to see the Pakistan president Asif Ali Zardari for a face-to-face bilateral meeting. In a press conference, Obama made a point of stressing that the only exchange he had with his Pakistani counterpart was short. “Very brief, as we were walking into the summit,” Obama said.

The US president said he “did not want to paper over the cracks” and that there has been tension between the US-led international force in Afghanistan and Pakistan over the last few months.

I’m not sure if this is a ramping up of tension, or a recognition by Obama that the military is running the show.

But the fact is that we are effectively at war with a significant portion of the Pakistani state security apparatus, which is actively destabilizing Afghanistan because they see Karzai as being to favorably disposed toward India.
