It was a month since President Gong Gyeong-dong of Jeoguk declared war on the culture of K-pop proclaiming it to be degenerate and corrupting, which was followed by mass imprisonment and even execution of K-pop fans, as well as the plotted assassinations of K-pop bands by rogue military officers. Feeling threatened and persecuted the K-pop fans of Jeoguk formed the Idol Devotees Defense Front (IDDF) which rebelled against Gong's government. Because Jeoguk's military was not ready and the IDDF had tens of thousands of K-pop fans from the world, but mostly China, joining it, the government lost control of a lot of territory in a few weeks.
This caused approval rates of President Gong to drop and many dissident scholars in Jeoguk to speak against his policies. As a response President Gong cracked down on dissent arresting and disappearing many opposition leaders. The rebels only became more popular and more rushed to defect or join. In addition the Jeo Revolutionary Army was made of several former army units that defected but refused to associate with the IDDF (although they are allied currently). The IDDF took advantage of this and claimed themselves to be a force for freedom and justice in Jeoguk to win international support.
Currently the rebels already control all territory north of the Iman River (Bolshaya Ussurka River) and west of Vostok, as well as the region west of Lake Khanka. Battles are raging in Yongwon (Spassk-Dalny but larger and touches the lake), and in Hwanju (Dalnerechensk). The government still controls most of the country but is in a vulnerable position. How could foreign intervention change this all?
