It looks like Bush has really painted himself into a corner on the transfer of Iraqi "sovereignty".
But coalition partners and some of his closest officials are sceptical that events on the ground will permit even the best laid plans to run their course. They are also concerned that the White House has no back-up plan if Mr Brahimi fails to put together a caretaker government by June 30.At least we can be pretty sure Ahmed Chalabi no longer has the inside track on running The New IraqTM.
Mr Bush recently told Silvio Berlusconi, the Italian prime minister, that the UN envoy was doing a good job and would come up with a proposed list of names within two weeks. But one senior official, who gave Mr Brahimi only a "60-40" chance of success, said there was no "Plan B".
