Of course, E.J. Dionne, Jr. wants to make the Libby pardon about the politics of the Iraq war. For him, Scooter Libby is a symbol of all the war supporters:
The Libby case put their generation on trial, to use Alistair Cooke’s evocative phrase about a very different trial in an earlier age. The verdict against Libby was a verdict against them.
This is, of course, ridiculous, implying (as he wants to) that making the case for the war was criminal: "Bush lied; people died; if there were any real justice in America, all the war supporters in the Bush Administration would be going to jail."
I know this is the position of many on the hard left and of some on the isolationist right. I’ve come not to expect more and better of Dionne, who was once an interesting and thoughtful columnist.
