I don't know about the US and other countries, but firebreaks are not really there to stop fire. Well, they do have that effect on some intensity fires, but the actual reason is enabling vehicle access. A fire of any reasonable intensity can easily jump a firebreak with a decent wind. And then there's spot-fires, which are like voodoo, you can be fighting a fire in front of you and have fires suddenly 300m behind you. All they really do is give you a point to fight a fire.
