Like disbanding the whole Iraqi army
Like not having the first clue about what to do after shock and awe.
Like ignoring the high probability of inter-ethnic warfare / civil war.
Like rejecting all criticism as BDS and/or traitorous.
Like ignoring the results of the UN Inspectors coz you just know they're a threat.
Like naively expecting a domino effect in the region.
Like expecting the whole country to welcome the invasion with flowers.
Like ignoring all successful counterinsurgency strategies of the past and going primarily with military action.
Like telling Iraqis we want to keep em safe, while telling Americans "Hey, Iraq is a honey pot, they're not bombing us!"
Like learning nothing from history when trying to place Sadaam in the role of Hitler, all detractors as Chamberlain.
Like letting the Taliban regroup in Afghanistan.
Like pretending Afghanistan has been rebuilt when all you secured was Kabul.
Like F'ing the whole thing up from start to finish through incompetency, ignorance and arrogance.
