Of course it doesn't change anything.
Plame's name was exposed when it was and by those who did it because their intention was to punish Plame's husband for not playing their little war game. They think they're untouchable and can do just as they please. Well, guess what! Their playtime is just about over...and so is Bush's.
The twisted logic of the Republicans is particularly idiotic in this case. Look at the weird rationale they are using:
Even though Joe Wilson was absolutely correct when he reported that Iraq had not attempted to buy uranium from Niger, he was not credible in his correct assessment, because his wife worked for the CIA.
The choice of Joe Wilson by the CIA for this mission smacks of nepotism, because his wife works for the CIA. Yet, he received no compensation for his efforts, and he even paid for the trip out of his own pocket.
Scooter Libby didn't out Valerie Plame, because he didn't actually use her name. He just said, "Joe Wilson's wife". Joe Wilson is very well known in Washington, and a Google search of Wilson instantly revealed the name of his wife.
Now, everyone is innocent because Presidential advisor Steven Hadley told Woodward about Plame a month before Scooter, Rove, Cheney, ect. went on their crusade to publicize her identity.
Prosecutor Patrick Fitzgerald has no case against Scooter, Rove, Cheney, ect. because he didn't know that Hadley was the first Bush administration senior official to out Valerie Plame to a journalist.
In this last instance, the Republicans and their puppydog press have rewritten history. This assertion is false:
...will Mr. Fitzgerald now say he was wrong to say on TV that Scooter Libby was the first official to give this information to a reporter?"
Here is what Fitzgerald said from the actual transcript of his press conference:
FITZGERALD: But Mr. Novak was not the first reporter to be told that Wilson's wife, Valerie Wilson, Ambassador Wilson's wife Valerie, worked at the CIA. Several other reporters were told.
In fact, Mr. Libby was the first official known
to have told a reporter when he talked to Judith Miller in June of 2003 about Valerie Wilson. Link
At the time Fitzgerald made that statement, Scooter Libby was indeed the first known
official to have outed Plame to a reporter.
However, the mainstream news media have, at the request of their masters in the Republican party, removed the word known
from any discussion about Fitzgerald's statement.
