US: 'We'll hit al Qaida anywhere'
The White House's top terror adviser said the US would keep targeting al Qaida anywhere in the world, including in countries unable or unwilling to do it themselves.
Counter-terror chief John Brennan laid out what could be called the Osama bin Laden raid doctrine, in remarks at Harvard Law School.
He said under international law, the US could protect itself with pre-emptive action against suspects the it believed presented an imminent threat, wherever they were.
That amounts to a legal defence of the unilateral Navy SEAL raid into Pakistan that killed al Qaida mastermind bin Laden in May, angering Pakistan.
Mr Brennan said the US preferred to work with countries where the targets hide, and to capture, not kill suspects, whenever possible.
