I find it interesting that the artist–whose anti-American sympathies can be taken for granted, chose to use a version of one of the most famous patriotic American images in existence, the flag-raising at Iwo Jima by the US Marines:
The artist even rendered the figures wearing a reasonable approximatination of Marine uniforms of the time. Interestingly, there is some echo in reality to this, because the Chechen mujahideen have frequently been photographed wearing American-style camouflage.
It could be that somehow the “Chechen Massacre” artworks was meant ironically, but aside from some glancing references to Somalia, Bosnia, and Baghdad the United States doesn’t figure in this poem, so I rather think not. This looks rather more like another of those moments like when the kid wearing the Coca-Cola t-shirt brandishes a photo of Bin Laden for the camera.
