A new book about Chirac and Bush reports that the U.S. bugged Chirac's phone calls during the buildup to the Iraq War:

"The relationship between your president and ours is irreparable on the personal level. You have to understand that President Bush knows exactly what President Chirac thinks of him," a US official is reported as telling a senior French military official in Chirac contre Bush: L'autre guerre, by journalists Henri Vernet and Thomas Cantaloube.

I remember reading somewhere that the U.S. was surprised when the French declared they would use their veto. But if they were listening to Chirac's phone calls, and if, as the book's authors claim, "there were 'no moderating elements' inside the [French] team," were they really surprised?

And if so, why?
