The bombing, the most brazen yet apparently in a campaign by militants to destabilize Pakistan, came at a critical moment for the new president, Asif Ali Zardari. While he has pledged to continue fighting militants — now thriving in the tribal areas near the border with Afghanistan — it was unclear whether he would face political resistance making it more difficult to keep that promise.
Who benefits from more destabilization in Pakistan?
The US and NATO.
When Zardari meets Bush at the sidelines of the UN General assembly meeting, expect that he will be further pressured to allow for more US and NATO airstrikes on his country to fight the militants.
Of course, we have seen what a colossal failure that policy has been in Afghanistan.
Aerial bombardment guarantees two things: they will kill a lot more civilians, and radicalize the Pakistani population even further against Zardari's government.
