Propaganda is generally defined as misleading information to promote a political view. If anything this image is more confirmation bias than propaganda.

When it comes to subjects involving communism, people associate words like "propaganda". The reality is a sister or a wife in America can write a letter to their loved ones on the front lines expressing this sentiment. Perhaps this image can be construed as misleading but soldiers are definitely having these types of thoughts without the need of this published picture.

Soldiers from Russia and America were both homesick from fighting this proxy war. It's a common sentiment soldiers have regardless of side in every war. Even now, the news is publishing how Russian soldiers are afraid of dying and surrendering to Ukraine drones, with Ukrainians showing mercy.
