But Rau technically never gave the N-Jammer Cancellor plans to the EAF...he sort of let...well destiny decide what would become of the plans...

he let Fllay float onto the battlefield knowing that if the EAF got a whole of it they would use nukes...and also knowing that ZAFT had Genesis and he hoped that both naturals and coordinators would destroy one another...

but letting Fllay float onto the battlefield also gave the Clyne Faction a chance to recover the disk and suppress that information...so really he just let fate decide...of course he didn`t think the nukes would be destroyed and that he would be the one to get fried by Genesis.
