Why "must?" That just sounds like an assumption based on what you want to be true. It is just as likely that a civilization you describe exists but has the exact same type and frequency of internal squabbles that humans do.
With that much power, "internal squabbles" equals mutual annihilation. Just imagine if terrorists could easily make their own thermonuclear weapon etc.
