it's not sensible it's pantomime logic.
The USA has never invaded a country illegally, never assassinated a democratically elected leader, has never secretly funded contras, has never astroturfed a protest movement, has never deliberately stirred up a destabilising war, never flooded a country with drugs, never carried out a black flag operation, is appalled by the idea of propaganda, never tortured anyone, isn't engaged in a geolopolitical battle to control the world and definitely has never undertaken an act of sabotage. To even consider that they might must mean dubious motives! A comforting world view I guess...
