Did US ignore intelligence about al Qaeda group offensive in Iraq?

Telegraph:

MI6 and the CIA were handed intelligence outlining the planned takeover of northern Iraq by jihadists and their allies five months ago but the British and American governments failed to act on it, senior officials in Iraq have told The Telegraph.

The head of intelligence for the autonomous Kurdish regional government, which has links with the West, said he had repeatedly tried to send warnings both to the central government in Baghdad and to its allies, Britain and America.

But despite repeated attempts to impress on Washington and London the seriousness of the unfolding situation, he said there was no response from either government.

The claims were made as it emerged that as many as 500 British-born fighters have travelled to the Middle East in recent months to take up arms with the Islamic State of Iraq and al-Sham (Isis).

There is more.

While initially it looked like an intelligence failure led to the offensive, but this suggest we ignored the intelligence we had.  I suspect Obama did not want to do anything anyway.
