Disinformation campaigns are targeting U.S. veterans through social media, seeking to tap the group’s influential status in their communities and high voting turnout in order to influence elections and fuel discord.

Back in 2017, Facebook was just another online tool for Kristofer Goldsmith, associate director for policy and government affairs at the Vietnam Veterans of America, or VVA. He used the site to update veterans on benefits and connect servicemen. But then he found out that someone else in Bulgaria had been trying to do his job.

Goldsmith stumbled on an impersonator Facebook page mimicking the VVA page — right down to the logos. The lookalike page shared manipulated news stories and memes meant to anger veterans, all posted by a page administrator based in Bulgaria. It was also significantly more popular than the genuine VVA page, with tens of thousands of more followers.

Goldsmith, 34, is a veteran of the Iraq War. “Finding this stuff made me feel that I was back in the fight against a real foreign entity that’s attacking the very thing we swear to protect.”
