Welcome to the madhouse ;)To get the idea as to why they'd do it look into the story of the Reichstag fire in Germany or Operation Gladio in Italy and then look up Operation Northwoods aswell as the PNAC document 'Defence Planning Guidance' (especially the part about 'a new Pearl Harbour'). Those things tell us all we need to know about means, motive and opportunity to carry out false flag operations. It's a tried and tested tactic I'm afraid.
