The only options in Iraq are:
1. Help the Sunni Jihadis take over iraq
2. Help the Shi'ite Jihadis take over Iraq.
3. Stay out and let them kill each other as long as possible, which means fewer Jihadis will return home to the US to practice their murderous trade.
The Choice is obvious.
As for our "sunk costs" and to those who lost loved ones in Iraq who ask "what was it all for?" The answer is IGNORANCE! The tragedy started in 2003. We intervened because of a paper written in 1988 that postulated "Democracies are not aggressive: therefore, install Democracies and we'll have a more peaceful world." The trouble is, Democracies are an Anglosphere tradition that doesn't transplant well.
In Islam, the Shari'a is "the rule of Allah", and government is considered a sacred function of Allah. Thus, to impose a legislature, where men govern and are presuming to "partner with Allah" is extreme blasphemy! Shirk! Haram! But no one in the West seems to understand this. I don't care how many purple thumbs there are, or how large the voter turnout is, the ideology will not permit it. And remember: the populations of Iraq and Afghanistan support the Shari'a by large margins.
And there's this: we have growing numbers of Jihadis right here in America. Why waste blood and treasure ten thousand miles away when we will soon need it here. We would be better off doing the following:
1. Declaring the Muslim Brotherhood a terrorist organization and shutting down their 4200 front groups in the US. This would include CAIR, MSA, IIIT, ISNA, NAIT, and all the rest.
2. Confiscate all their assets, and use the funds for Counter Jihad education and operations. Take over the "Centers for Islamic Studies" at Universities which are basically Jihadi propaganda mills.
3. Arrest and imprison all the Muslim Brotherhood operatives in the front groups and those that have infiltrated the US Government, and that would include a large number of White House advisors
4. Monitor every "Fortress of Faith" and Islamic Center that serve as Jihad recruiting, training and deployment centers.
5. Arrest, deport and / or imprison any Imam or Mullah that preaches "death to America" or "Death to the Jews" and shut down the Masjid immediately, (searching it for bodies and stored weaponry).
This would be a start
