I hope the clerics in Najaf do the right thing and tell these squabbling politicians to get their act together and shoulder responsibility. After all, they are the elected officials. If the next government of Iraq fails because of decisions taken in the offices of the clerics in Najaf they would enjoy the same level of respect their counterparts have in Tehran. This has disaster written all over it.
The senior clerics in Najaf adhere to their own version of 'collective responsibility' similar to that practiced in Westminster-style governments. They may disagree in private and debate each other but when the senior cleric makes a decision, the others will defend it publicly. If Sistani does reject this offer, it is wonderful news because the other three Grand Ayatollah's will refuse to be dragged into this game of cat and mouse with the Iraqi politicians. Fingers crossed he will.
