The common expression "a bad world is better than a good quarrel" often makes people put up with the injustice, aggression, rudeness and selfishness of others. Meanwhile, if you look, then by no means always this maxim corresponds to the truth.
Politics and Diplomacy
Historically, the idea that strained peaceful relations without open conflicts is better than noble, but still battles, has emerged as one of the principles of state diplomatic policy. In fact, any military confrontation brings many problems to states: huge costs, loss of morale, loss of capable population, destroyed infrastructure - all this made politicians and diplomats come to the conclusion that military operations should be avoided to the last. In the end, there are many other ways to demonstrate your own intransigence, while avoiding casualties and destruction, such as customs duties.
