http://news.bbc.co.uk/1/hi/world/americas/4436860.stmI have taken various paragraphs out, and have not indicated the snips--but it looks like the Brits have got it right in this article.
According to Tom DeFrank, who was Ch*ney's counsel before the war,
"There is a feeling on the part of the president, according to people very close to him, that the president got unwise political advice and rosy predictions of how a war and post-war in Iraq would play out."
"There is also some feeling on the part, not only of the president but also some of his closest political advisers, that the Cheney national security operation got a little too ambitious and became too independent of the Bush and state department national security apparatus, and some aides very close to the president are determined that that will not continue."
Rise of Rice
Since January, the vice-president has also had a new political counterbalance, in the form of Secretary of State Condoleezza Rice - a close personal friend of Mr Bush.
Unlike her predecessor Colin Powell, Condi, as the president calls her, is known to have Mr Bush's ear - and she has used that lever to take firm control of foreign policy.
Add to that Mr Cheney's recent humiliating failure to stop the Senate passing new guidelines for the treatment of detainees - and the vice-president no longer looks all-powerful.
Even the Democrats see him as a weakness worth exploiting, with Senate minority leader Harry Reid saying the vice-president was involved in the "manipulation of intelligence to sell the war in Iraq" and that America could do better.
