The Founders' extreme longevity (indeed, practical immortality) has provided them with a uniquely long viewpoint. As the genetically-engineered and highly intelligent Jack described: the Dominion does not adjust its strategies based on what has occurred within the past week or even year, but is concerned instead with what the universe will look like centuries or more forward. This perspective was evident in the Dominion War, where the strategy was to engage in a long-term war of attrition, counting on superior construction methods and their ability to breed Jem'Hadar, rather than risk everything on one battle.
