The poster shows the mug shots of two Cuban spies – Ana Belen Montes, impassively staring straight at the camera, and Walter Kendall Myers, almost arrogantly looking down his nose.
"A nation can survive its fools and even the ambitious. But it cannot survive treason from within," says the text above the photos, a quote from an ancient Roman philosopher. "True Then. True Today," it says below the photos.
Montes and Myers, serving long prison terms for their treasonous service to Cuba, have become poster persons for a campaign on the dangers of foreign spies similar to the "Loose Lips Sink Ships" posters of World War II.
Veterans of the U.S. intelligence community said their appearance sends a clear message: that Cuba’s intelligence services remain a threat to U.S. interests.
