The Pentagon has a web site for the unexpected current operations against ISIS (ISIL/IS) made necessary by the failure to responsibly end the war, but as yet no name for the operation.
Perhaps Operation Degrade and Destroy (ODD)? Or maybe Operation Desert Drizzle? (No Storm this time.)
Operation ISIS Liquidation (OIL)?
Operation Bush's Fault (OBF)?
Despite the length that rules it out for official acronyms, I'm leaning toward Operation Seriously, No Alibi Possible (OSNAP).
Our military will perform their duty to the standards we have come to expect from our people.
Sadly, they are lions led by donkeys. The question is how our civilian leaders will use our mlitary.
