Johann Hari worries:

First, the good news. Some worthwhile safety precautions have been put in place in Pakistan over the past five years. The country’s nukes are not kept on hair-trigger alert, ready to fire at any moment. Instead, the warhead cores are kept in different places from the weapon detonation components. To put them together and make a shootable nuke would take around three days – providing a long(ish) fuse in a crisis. Even if jihadis managed to seize one nuclear weapons site, they would still need to seize another one – and secure transportation between the two – to go nuclear.

Nothing else about this picture is reassuring...
