The way I interpreted the image was 20 years after 911. People fell from the towers. It was horrible and gruesome, but we should remember them always. After this event, a lot of things happened that may or may not have been necessary, but now we are here. It's part of our past.
There are no political debates allowed on this forum. Some art that's posted might depict certain political stances, and that's fine. We all can voice our interpretations. But once blatant, or disagreement or harassment about these kinds of subjects arise, don't be surprised if the thread gets closed. It's just a rule we have here that we all stay on point with art, not anything else.
