Charles Krauthammer thinks it is not an unreasonable suggestion. I dont know if he is right but, it does seem to me that the objections to it--if they are as he describes in this article--are pretty silly and outdated.

The old alliances of post-WWII America may need some re-sorting, dusting off, additions and subtractions. This piece is a good device for starting that discussion.
