I think it will be argued that the recent NIE report that showed Iran suspended its nuclear program in 2003 is true: they simply moved it to Syria once it was sure we were going into Iraq.
And maybe it will be shown that Saddam moved a bunch of his WMDs for Syria to hold, once they realized same.
Israel has solid-metal proof of NK sending not just fissionable material but probably actual components and maybe something semi-functional to Syria.
