The take away here isn't Waco or even Viet Nam (because the VC had the support of North Viet Nam and later the conflict was carried by the NVA), but Oklahoma City. You cannot wage a symmetric conflict with the government and expect to win. This is going to be a conflict of assassination and ambush - this Kongressional staffer here that bureaucrat there etc. IEDs in the favorite speed trap hiding place. It has the potential to get real ugly
