I've been searching lo these many years for an image of Mark Twain astride a globe. I had been searching for Benevolent Assimilation Society, thinking it was a Mark Twain irony on the imperial ambitions of the United States.
Ho, was I wrong! The US actually used the term "benevolent assimilation" describing their conquest of the Philippines. Searching on something related, which I've already forgotten, I found the image. Huzzah! Mark Twain was a member of the Anti-Imperialist League, and that's the inspiration of the cartoon.
