Wartime propaganda has evolved for the social media age, and Iran is now vying with the U.S. to be the world’s biggest keyboard warrior.

As the real-world bombardment in the Middle East continues and casualties mount, both sides in the month-old war are also firing off ironic, pop-culture-steeped memes on the online battlefield. Iran’s new leaders have quickly assumed an online fighting posture, amping up their memes and pointed attacks on the U.S. and Israel.

“What we’re seeing is not just a war of weapons, but it’s also a war of aesthetics,” said Nancy Snow, a professor and author who studies propaganda. “Whoever controls the meme controls the mood.”

Iran’s prime target is President Donald Trump, with state media and top officials alike relentlessly mocking and amplifying criticisms of the U.S. leader.

Top members of Iran’s parliament, its Islamic Revolutionary Guard Corps and even its president, Masoud Pezeshkian, have sought to insult or undermine Trump in their messaging. And they’re using the world’s most popular social media platforms, such as Facebook and X, to get the word out.
