Oh, they're not that arrogant. Not by a long shot. The Great Empire and the United Republic have a cold war thing going on. They're avoiding each other because fighting is Mutually Assured Destruction.

That's not even human arrogance. That's stupidity. As a species, we're arrogant, but we're able to recognize external threats pretty quickly. It's sorta how we're not dinosaur meat by now.
