I also urge the Obama administration - both on its own and in cooperation with other responsible governments around the world - to use all legal means necessary to shut down WikiLeaks before it can do more damage by releasing additional cables. WikiLeaks' activities represent a shared threat to collective international security.

In my role as Wikileaks editor I've been involved in fighting off many legal attacks. To do that and keep our sources safe we have had to spread assets encrypt everything and move telecommunications and people around the world to activate protective laws in different national jurisdictions.
