Dialogue is the number one strategy to solve unwanted fights.
You want dialogue to be a habit.
Imagine two countries in tension.
Imagine what would happen if they were simply attacking each other the moment they disagree on a topic.
What happens instead? They solve their disagreements in a diplomatic way. Dialogue! You don't grab your weapons; you sit down and discuss the issues together. The goal is to create synergy. The goal is to create win-wins. You want everyone to be a winner in conflict situations.
To do this you need to sit down and talk. There is no way around it.
