SEATTLE — As protests over South Korea's ballot shortage controversy continue, many foreign observers are asking an unusual question: Why are American flags being waved at a protest over a Korean election?

Images from the demonstrations show participants carrying U.S. flags alongside South Korean national flags, renewing a long-running debate over the symbolism of the Stars and Stripes in Korean politics.

The question has surfaced across social media platforms including Reddit, X and Threads, where expatriates and international observers have debated why a foreign flag has become a recurring feature at some Korean political rallies.

"It's so bizarre seeing so many American flags," one user wrote.
