The Iranian missiles  in Iraq are not precision guided and the US is worried because civilian deaths might cause sectarian strife.  

The bombs the US dropped on Baghdad in its Shock and Awe Operation were not precision guided,  and they didn’t cause sectarian strife.  Did they?

The US now has a choice:  give Iraq precision-guided missiles or do all the heavy lifting itself.  It is unseemly for the US to stand on the sideline and carp.

Iran Sent Arms to Iraq to Fight ISIS, U.S. Says

By ERIC SCHMITTMARCH 16, 2015

WASHINGTON — Iran has deployed advanced rockets and missiles to Iraq to help fight the Islamic State in Tikrit, a significant escalation of firepower and another sign of Iran’s growing influence in Iraq.

United States intelligence agencies detected the deployments in the past few weeks as Iraq was marshaling a force of 30,000 troops — two-thirds of them Shiite militias largely trained and equipped by Iran, according to three American officials. The officials spoke on condition of anonymity to discuss sensitive intelligence reports on Iran.

Iran has not yet launched any of the weapons, but American officials fear the rockets and missiles could further inflame sectarian tensions and cause civilian casualties because they are not precision guided. Their deployment is another dilemma for the Obama administration as it trains and equips the Iraqi military and security services to help defeat the Islamic State, but unlike Iran is unwilling to commit fighters and advisers who join Iraqi forces in the field.
