Who's to blame for Iraq crisis

Why don't you ask Iraqi Prime Minister Nuri al-Maliki a shite who's governd Iraq like a dictator since his installation in said office with the backing of the Bush administration.  al-Maliki has created the current crisis in Iraq through his lust for power and his willingness to marginilize Iraq's Sunni minority who could have helped him maintain control over the whole of Iraq instead he chose to create an enemy where none need exist.

The politicization of the Iraqi military

For more than five years, Prime Minister Nuri al-Maliki and his ministers have presided over the packing of the Iraqi military and police with Shiite loyalists -- in both the general officer ranks and the rank and file -- while sidelining many effective commanders who led Iraqi troops in the battlefield gains of 2007-2010, a period during which al Qaeda in Iraq (the forerunner of the Islamic State of Iraq and Syria) was brought to the brink of extinction.

Al-Maliki's "Shiafication" of the Iraqi security forces has been less about the security of Iraq than the security of Baghdad and his regime.

Like the deBaaification of Iraq's civil servants which completley backed fired on the Bush administration.  Iraqi government has caused the Sunni minority to join forces with militants whom they see as conduant for the removeal of the al-Maliki government.

The dismantling of the 'Awakening'

It's no accident that there exists today virtually no Sunni popular resistance to ISIS, but rather the result of a conscious al-Maliki government policy to marginalize theSunni tribal "Awakening" that deployed more than 90,000 Sunni fighters against al Qaeda in 2007-2008.

These 90,000 "Sons of Iraq" made a significant contribution to the reported 90% drop in sectarian violence in 2007-2008, assisting the Iraqi security forces and the United States in securing territory from Mosul to the Sunni enclaves of Baghdad and the surrounding Baghdad "belts." As the situation stabilized, the Iraqi government agreed to a plan to integrate vetted Sunni members of the Sons of Iraq into the Iraqi army and police to make those forces more representative of the overall Iraqi population.

al-Maliki only interested in his own surrivial never intergarted any Sunni military or police offiers into the countries security apperatous.  

Given that the Iraqi government is allied with Iran what happens when the government in Terhran concludes that the situation in that country has become untenable and deploies troops across the border in an effort to shore up the Maliki government?

Could that lead to a wider conflict in the region? Perhaps given that the other countries bordering Iraq are majority Sunni.
