I had to watch it again, as I didn't understand what was happening, but once I read your description it made sense; maybe I didn't understand at first why a white flag was standing on a hill in the middle of nowhere. Maybe some animations could be more clear, like the president pressing the red button. Also at the end, the bomb kills the guy with the binoculars and the people with him, which also adds a bit to the confusion.
I had to watch it a second time because at first I didn’t fully understand what was happening. After reading the description, the idea made sense, but initially it wasn’t clear why there was a white flag on a hill in the middle of nowhere.
Some animations could be clearer, for example the president pressing the red button. Also, in the ending, the explosion kills the character with the binoculars and the people next to him, which added a bit to my confusion about what the final message was.
