Well, if it's Biden, it's going to have to be something that he can say he's been saying for the last whatever number of years. It is VERY important to him to have been right from the start...even if he hasn't been saying any such thing. Jon Carry does the same thing. It's a mental defect of some kind.
Biden claims he was for Iraq partition to three separate states. He conveniently forgets this was discussed years ago and rejected. If I remember right, there were concerns with Turkey accepting a nation of Kurds as well as division of oil production ownership and the prospect of more bloodshed between them all claiming territory. Biden talks like this is a new idea.
