Actually, that's not completely true. There is open debate (and there has been for centuries) whether or not in the very very very rarest of cases where grave necessity would necessitate it, that a priest could ordain a priest and/or consecrate a bishop.
Certainly though, this is not one of them.
I thought that was decided in Japan. When the priests there died out, there was no bishop and the Japanese Catholics sustained themselves solely through baptism without a clergy for generations until the Church was able to provide them with pastors again.
