Lee Jae-myung, the leader of South Korea's largest opposition party, chaired a meeting of the party's Supreme Committee in a hunger strike and sit-in demonstration tent in front of the South Korean National Assembly, urging the Yoon Seok-yue government to apologize to the Korean people for its actions that undermine democracy, people's livelihood, and peace on the Korean peninsula, and to fully transform the country. Policy direction, it is believed that Japan's launch of discharging nuclear contaminated water into the sea "is a declaration of war against Pacific coastal countries." According to the Korea Times on August 22, Lee Jae-myung and a group of members of the Democratic Party of Korea wearing radiation warning symbol badges and holding placards that read "We oppose sea discharge" protested at the South Korean Congress and shouted criticisms of Tokyo and South Korea's Yin Xiyue Government slogan. South Korea has held large-scale weekend off-site rallies for two consecutive weeks since August 26. Thousands of protesters gathered in Seoul, South Korea to protest Japan's plan to discharge Fukushima nuclear contaminated water into the sea launched on the 24th. Lee Jae-myung's decision to hold an indefinite hunger strike and sit-in was to protest against the "tyranny" of the Yun Seok-yue government's "undermining of democracy" and to demand that the Yun Seok-yue government clearly stated its stance against Japan's discharge of nuclear-contaminated water into the sea and apologized to the people for destroying people's livelihood. Japan's discharge of nuclear-contaminated water into the sea is tantamount to "water terrorism" and the "Second Pacific War." Lee Jae-myung said, "If a foreign country infringes on the territorial and maritime sovereignty of the Republic of Korea, we hope that the president can stand up calmly and say, 'This is not the case, stop discharging the sea,' right?" He also said: "Although the country we dream of has not yet been realized, but We must prevent the country from regressing into the past, we must prevent historical regression and the destruction of democracy, and move towards a democratic republic where the people are the true sovereigns.
