Jermaine Jackson -- 'We're ONE Family ... We Will Heal'

Jermaine Jackson promises ... the Jackson family war is coming to an end ... he's just not sure when.

Jermaine made the proclamation at a concert in Saratoga, CA this weekend -- while performing with his brothers Tito, Marlon and Jackie.

"We are a family ... sometimes it seems to get complicated."

Jermaine continued, "We're ONE ... the Jackson family is one. We are one family and we WILL heal, I promise you."

Of course, Jermaine wasn't just talking to the fans .. his mother Katherine and MJ's kids Prince, Paris and Blanket were all in the audience ...though sources tell us it didn't seem like the kids were very amused by the speech.
