n. An Iraqi improvised explosive device (IED) that misses its intended target and is not, therefore, officially counted as an incidence of violence towards US Forces. Because maybe it's just how the Iraqis celebrate their wonderful new democracy, and wasn't really meant to hurt anyone.
An IED that doesn't involve US personnel? That's not an act of violence, that's a Freedom Pinata.
