Obama outlines new US foreign policy approach

President Obama has signalled a change in US foreign policy and a narrower definition of what the 'war on terror' constitutes.

He has announced that the use of drones will be limited to situations of 'imminent' danger to the US, has switched responsibility for launching a drone attack from the CIA to the Department of Defence, and overturned a ban on transferring Guantanamo detainees to Yemen.
