What are you on about? The Dutch army was not capable of dishing it with Louis XIV's army.
When we compare things to Napoleon's extent then they do seem small but monarchs did not go around annexing territory willy-nilly. England's contribution on land has always been very little.
Turenne had gone past the water line, the Dutch were in trouble.
Louis XV (the Useless as I like to call him) had quite a long rein during which things varied a lot.
Getting Belgium is not a problem, France managed to take it all despite their mismanagement of the army. The only one eho cared about it for a rematch, England, was incapable of taking unilateral action.
Giving it back was silly.
