Well, it was an insane thing for Graham to have said this publicly, but it is clearly what many people, including those in a position to effect it, are thinking privately. It may well be the way this thing ends.I mean, Putin has basically threatened to nuke anyone who crosses his line. I think many of us in the west feel he is threatening similar to whole societies.
It was likely an unwise statement from Graham for various reasons related to international diplomacy, though.
I rewrote the above so many times to try not to appear to be saying something I am not saying that I will just leave it at that.
