Is flutter speed always smaller than divergence speed for aircraft?

WebWings for most transonic aircraft will have some sweep, of necessity, just to increase the drag divergence Mach number. Those commercial or bomber aircraft will need to maintain high lift/drag for cruise efficiency, and this can be accomplished by having the wing sections effectively sheared aft, resulting in a high aspect ratio planform.
