Watch this video.
From here on out, whenever you hear about war, remember this video.
From Wikipedia:
“It features a young British girl experiencing the effects of a hypothetical civil war on the streets of London. Everything depicted in the video was based on the factual accounts of children in Syria. The video’s purpose is to depict the lives of children growing up surrounded by war, in order to bring attention to young people caught up in the Syrian Civil War.” The video is from 2014.
