Who is a buddist leader?
I believe a major Buddhist political and religious leader is the Dali Lama, who was exiled from Tibet some while ago. He still helps his home country out though...they were owned or still owned by china...i can't remember.
According to wikipedia, he is a Jewish-Buddist, someone with Jewish beliefs who meditates using Buddist methods. Both Jewish and Buddhists have segments that do not believe in a god of any kind, being a practicing, meditating Jewish-Buddist does not inherently mean belief in a deity. Robert Downey Jr. is actually an atheist.
