But the point was he was using his masters/teachers, and bringing the Kazekage in would have been detrimental to the situation as Suna would have realized what really happened a lot earlier. Now I know your about to say Yondiame doesn't fit either. But he would fall in line better than anyone else. And again it didn't say 4th, it didn;t say anything, because we didn't see it. But as far as who I almost forgot that he could have used someone like one of his teachers before Shodai and Nidiame took over teaching him.
