the French withdrawl from NATO in 1967

when France announced the intention towithdraw from the military component of NATO in 1966, it is frequently asserted that LBJ (or someone) asked de Gaulle “What about our dead in your war cemetaries, do you want them withdrawn too?” or similar words. Can anyone provide a citation for this story, or is it just ‘one of those things that everyone knows’?
Snopes, in http://www.snopes.com/politics/military/garbage.asp attributes it to Dean Rusk, without offering any citation. I have also heard, on another board, that it was a newspaper cartoon featuring two ghosts in WW1 and WW2 GI uniforms peering over de Gaulle’s shoulder and saying, “What about us, Charlie, do you want us to go home too?”
Can anyone offer any more information?

Actually, Snope provides three citations:

Presumably I have access to these through my university. If you need help getting them we can correspond over e-mail.

Cheers,

I first read of this in an article by William F. Buckley, Jr. in The National Review. His version had de Gaulle telling Dean Rusk that he wanted all US soldiers out of France. Rusk was supposed to have replied “Including the ones in the cemeteries, General?” I can’t find a link to what I remember reading. I found a link to a quote by Charles Krauthammer telling the same story, but that is second-hand. The whole thing may be apocryphal.

I seem to remember that it was the U.S. ambassador, either to France or NATO. I forget his name, but he may have been a WW2 veteran himself. Can’t find a cite, alas.
