When Sir Carter woke up last Saturday, the world seemed pretty bleak.

A day before, President Donald Trump had ordered an airstrike in Iran that killed Gen. Qassem Soleimani. Everyone on social media was talking about this being the beginning of another world war, fretting about the possibility of further violence and the civilians who would get caught in the crossfire.

For Carter, 18, it was all very new and scary.

"Especially for this generation, we’ve never really experienced anything like this," he told BuzzFeed News. "Just kind of the reality setting in that this could potentially happen is very scary for people in my generation."

Social media wasn't just full of fear, it was full of memes. Jokes about World War III and the draft returning were all over every platform, from Twitter to Instagram to Reddit to Facebook. Like thousands of others, Carter opened his current favorite platform — TikTok — and joined in.
