The Americans have blamed MI6 for the forged documents they used as proof of Iraq's WMDs.

Possibly true - there's a reason the phrase 'good old British incompetence' exists.

But would the British Government be so keen to get involved in an unnecessary war?

Was Blair really that desperate to eliminate Saddam's regime? It certainly wasn't like he needed a post-Falklands surge in popularity. He'd have been more popular if he'd opposed the war on humanitarian grounds?

Alternatively, is this another example of the Bush administration's 'Oops, we fucked up, but hang on, it was their fault' strategy?
