Official Iranian news sources report on Prime Minister Nouri al-Maliki's visit to Teheran:
Iraqi Prime Minister Nuri Al-Maliki said Baghdad in its ties with other countries only acts based on the interests and demands of the Iraqi nation. The office of the Iraqi Prime Minister on Saturday in response to a warning by the US President George W. Bush against Baghdad’s development of ties with Tehran announced in a statement: The groundless warning was issued with the aim of overshadowing the successful achievements of Mr Al-Maliki in his recent visit to Tehran.The Iraqi Prime Minister’s office further announced: If the US President assumes that the level of Iraq’s ties with other countries would be determined according to his views, then he is wrong.George W. Bush on Thursday on the second day of Maliki's visit to Iran repeated his baseless claims that Iran interferes in the internal affairs of Iraq. This is while Nuri Al-Maliki on the same day appreciated Iran for helping Iraq establish security and stability, calling for expansion of ties with Iran.
It seems obvious to me that the takeaway here is that we should stop expending vast amounts of resources mucking around in Iraq, but I suppose one could take the Ken Pollack view that this means we need to sink deeper into the muck by deposing (but by no means ousting) Maliki's government and trying to find a more helpful client.
