I linked a video, because we know he's fine. He talks to the tank driver after climbing up on the tank, then leaves. I don't think a picture of the PLA showing patience after leaving the square does much for your point.
Yes, hundreds of protestors were killed, and many PLA officers lynched and burned alive, and more. Nobody denies that. However, showing a dude who we know lived is not the own you think it is, nor does it say anything about US Imperialism being "nicer." The US at the time was of course preparing for the Gulf War, which would set the stage for US Imperialism to result in 1 million Iraqi deaths under false pretenses of WMDs.
