I'll certainly go along with your premise that the U.S. does not always have clean hands, and certainly in the fates of Iraq and Afghanistan we were the prime movers, but I don't accept the notion that every coup and civil war in the world was engineered by the U.S.A.  For one thing it's insulting to the people of Venezuela and Yemen to insinuate that they needed our help in bringing their respective countries to their current state.  Certainly we often have a preference in the outcome, but in most cases I don't think we have either a strong motive nor the capacity to achieve the current conditions in a country like Venezuela, which I believe Chavez, Maduro and various opposition groups have all been capable of achieving all by them selves.  One still sees references to how the CIA overthrew the Lumumba government in DRC and installed Mobutu in his place, when history pretty clearly shows that that coup was actually engineered by Belgium.  Please lay credit where it is due.
