Invasion of ChinaEdit
Following the Liberation of Alaska, the US army began to invade China. With support from the China Liberation Front (CLF), they were able to carve a deep hole into communist territory in order to defeat Red China by invading cities like Shanghai and Hong Kong. Both were successful and Operation Redsky soon began, but were forced underground by nuclear retaliation from the United States.
After the Great War, the remaining US troops had begun to try to rebuild society, while US troops in China who survived, had begun to end communism in post nuclear China.
