Those who question whether the Americans would seek to destabilize the governement of an ostensible ally like France would do well to read up on the time they overthrew the Australia government back in the 70s.
John Pilger (yes, I know, but stopped clocks and all that) sketches it out here. He doesn't mention that the coup couldn't have occurred without the collaboration of Bob Hawke, at that time the head of Australia's union movement, who refused to call a general strike which might've neutralized the plot. Within a decade, Hawk would be parachuted into the office of Prime Minister and decades later we'd learn that our most cartoonishly Australian leader was in fact an American agent.
