The question now, and for the next few months, is whether the West will somehow become more engaged inside Pakistan. It's notable how British ministers have increasingly namechecked the country when justifying our presence in Afghanistan – but, still, it seems that the Taliban and other Islamist groups have strengthened their foothold there. And, if today's claims are to believed, they are now striking outwards.
Either way, whoever wins this week's election faces an international situation every bit as ominous, and as tricky, as our domestic woes. The next Prime Minister's position will hardly be enviable.
