There is a movie called “The Godfather”, which depicts a fictional war between mafia families in the US. In the film, there is an older generation that operates on a kind of respect system, and attempt to keep each other reasonably balanced, in both power and money terms. A drug dealer enters the picture, and attempts to murder Michael Carleone’s father (who is the Godfather). In response, Michael plans to meet the drug dealer and a corrupt police captain, sneak a gun into the meeting, and shoot them both. That plan works.

Later, the Godfather dies, Michael takes over as the head of the Carleone family, and plans assassinations of all of the older generation of every other family in a coordinated attack, during his father’s funeral. That plan works too, leaving him as the most powerful survivor.
