On MSNBC on Friday, retired Gen. Barry McCaffrey described President Obama’s decision to go to war in Iraq as a “pinprick” action to placate “internal U.S. politics.”

The Pentagon announced Friday that two F/A-18 aircrafts had launched two missiles against ISIS artillery in the region.

McCaffrey said he was concerned by the lack of a clear military objective and the use of “decisive force” in the new mission to Iraq.
