It used to be a conspiracy theory.

Now the only question is the extent to which she did that.

There is good evidence that the magazine was also paid for by the 3 letter agency.

In the 40s was intense and widespread hands-on war time patriotism that involved almost everyone at every level: draft of most men of age; rationing including melting silverware etc; companies diverted to war materiel; even citizens financing the whole thing with war bonds.

Then the Stalinist Russians, with some 5 million people in the gulags, became nuclear in 49. The Rosenbergs were executed in 53. This was some scary, tangible stuff. All that red scare whipped into a frenzy by Hoover and McCarthy built on all that wartime patriotism.

So I don't find it surprising that a few celebrities visiting abroad might write up a few trip reports or befriend diplomats, doing their part to keep the red menace at bay.
