From which it emerges that the CIA ran a culture war with the Soviets, and promoting Abstract Expressionism was part of it. Whether Rothko or any of the other artists was aware of it is another matter:

"Regarding Abstract Expressionism, I'd love to be able to say that the CIA invented it just to see what happens in New York and downtown SoHo tomorrow!" he joked. "But I think that what we did really was to recognise the difference. It was recognised that Abstract Expression- ism was the kind of art that made Socialist Realism look even more stylised and more rigid and confined than it was. And that relationship was exploited in some of the exhibitions.

"In a way our understanding was helped because Moscow in those days was very vicious in its denunciation of any kind of non-conformity to its own very rigid patterns. And so one could quite adequately and accurately reason that anything they criticised that much and that heavy- handedly was worth support one way or another."

To pursue its underground interest in America's lefty avant-garde, the CIA had to be sure its patronage could not be discovered. "Matters of this sort could only have been done at two or three removes," Mr Jameson explained, "so that there wouldn't be any question of having to clear Jackson Pollock, for example, or do anything that would involve these people in the organisation. And it couldn't have been any closer, because most of them were people who had very little respect for the government, in particular, and certainly none for the CIA. If you had to use people who considered themselves one way or another to be closer to Moscow than to Washington, well, so much the better perhaps."
