Well, we knew from the beginning that US forces in Iraq were receiving training from the IDF, but who knew we’d learn so quickly?
1. The Events
19 May 2004, Israeli helicopter and tanks fire missiles and shells into a crowd of Palestinian protestors in Tel Sultan, Gaza Strip, killing eight civilians including four children.
13 Sept 2004, US helicopter fires missile into crowd of Iraqis milling around a burning Bradley fighting vehicle, killing 13 civilians.
2. The Fog of War
IDF spokesmen –
"They were killed by their own bomb".
"We did fire missiles, but not at the crowd".
"We did shoot at the crowd, but at least five of the dead were armed".
"One of the dead was armed".
"We’re not sure that that one was armed after all".
U.S. spokesmen  –
"There was small-arms fire at the helicopter".
"We fired to 'save' the crowd".
"We had to keep the Bradley armaments from falling into the wrong hands".
"Someone was waving a terrorist flag".

4. The End Result
It took the Israelis 38 years to descend this far, and we've managed it in 18 months. We really are #1.
