I see where Paese Sera is briefly mentioned at the end, but where does DiEugenio debunk Weiner's article?
You only have to go to Wikipedia to see that Tarbot is as big a conspiracy fruitcake as DiEugenio and most of his apologists at JFK Ed-Forum.

"Talbot's book The Devil's Chessboard: Allen Dulles, the CIA, and the Rise of
America's Secret Government is a biography examining the career of Allen Dulles.
According to Talbot, Dulles orchestrated the assassination of Kennedy at the
behest of corporate leaders who perceived the President to be a threat to national
security, lobbied Lyndon B. Johnson to have himself appointed to the Warren
Commission, then arranged to have Lee Harvey Oswald take sole responsibility
for the act. The book charges that the conspirators in JFK's death also murdered
Bobby Kennedy as they perceived him to be "a wild card, an uncontrollable threat"
that would reveal the plot.

The book has stirred debate about the history of the CIA. In a review for the
San Francisco Chronicle, Glenn C. Altschuler stated, "Talbot’s indictment is long,
varied and sensational." Altschuler wrote: "Animated by conspiracy theories, the
speculations and accusations in his book often run far ahead of the evidence, even
for those of us inclined to believe the worst about Allen Dulles."
David Talbot spouted his lies and misinformation on-screen in "JFK Revisited". Fred Litwin sorts out his Talbot's false claims.

I'm open to the probability that Dulles had nothing to do with with the French coup attempt. The details are too murky to know what the truth is.
However, Weiner is wrong to imply that the Soviets were the source of the suspicions of CIA involvement and DiEugenio is correct that it originated from multiple sources, including the French security services.
On David Talbot, his book on Dulles is a very informative biography. I recommend it. The speculation about Dulles' role in the French coup attempt and the Kennedy assassination comes towards the end of the book and Talbot makes it clear that he was speculating about what role Dulles may have played in those events.
If you don't trust Talbot, Stephen Kinzer wrote a great book about the Dulles brothers too ('Brothers').
No one knows the absolute truth about any historic event. Often times, historians must speculate to fill in gaps. Which apparently, you think is a bad thing even though it's a common academic practice...
