This is an idea first proposed by Vice President Biden in 2006 when he was a senator. It was a non-starter then and it won't work any better today. While the Kurdish region in the north is already almost an independent country, neither Shiites nor Sunnis are interested in splitting up the rest of Iraq—something that would be hard to do, in any case, because the two sects are intermingled in Baghdad and other areas. Just as the solution to Iraq's last major bout of bloodletting, in 2003-2007, wasn't partition, so it isn't today.
With its Shiite government struggling for survival and poised for a confrontation with Sunni extremists in Fallujah, Iraq faces a deepening sectarian conflict partly fueled by spillover from Syria, says Jane Arraf.
"There is not a Sunni region in the country now that is not enmeshed in strife.… The conflict in Sunni regions is creating an atmosphere of perpetual crisis that could tip the country into civil war or be used by Maliki as a justification to stay in power after what is expected to be a closely fought election. The more chaos, the greater the chance for al-Qaeda-linked fighters to hide among the population and reap chaos."
Concerning the United States' legacy in Iraq Meghan L. O'Sullivan writes, "Had Saddam not been removed, it is almost certain that we would still be facing a volatile and potentially even more dangerous Middle East."
According to Meghan L. O'Sullivan, "Given the several still-undetermined variables and the wide variety of plausible outcomes, it is too early to bring final judgment on American efforts in Iraq even 10 years on."
