If the Korean government changes this regulation will this lead to the Korean leftists to start another mad cow crisis like what happened in 2008?:

The U.S. nationwide cattlemen’s group asked the Trump administration Tuesday to help lift South Korea’s import ban on American beef from cattle aged 30 months or older, noting that similar curbs have been lifted in China, Japan and Taiwan.
The National Cattlemen’s Beef Association (NCBA) sent its comments to U.S. Trade Representative (USTR) Jamieson Greer as the USTR has requested those comments to “assist in reviewing and identifying unfair trade practices, and initiating all necessary actions to investigate harm from non-reciprocal arrangements.”
The age restriction on U.S. beef was put in place in 2008 amid fears over mad cow disease, or bovine spongiform encephalopathy.
You can read more at the link, but the violent mad cow riots in 2008 has to rank up there as one of the most ridiculous anti-US protests ever in Korea. The 2000 Yongsan Water Dumping Incident protests are probably the only ones more ridiculous than the mad cow riots.
