Massive armies would rush over the DMZ, with more than 6000 artillery first opening up hell on them a few hours before, bombarding them with thousands of shells. This should cause considerable chaos and confusion on the South Korean army side, giving time for our armies to swarm over and force them back due to our sheer numbers, as well as thousands of tanks, armored cars, IFVs, and even attack helicopters supporting the advance, we would attempt to reach Seoul within 2 weeks, and then establish a new fortified line against the South Korean armies while waiting for orders for a second offensive. Meanwhile, Japanese islands far south of the mainland would be immediately targeted, and we will send 10K troops towards those islands to quickly capture them, with the support of coast guard vessels. The majority of our navy would establish a large naval blockade over the South China Sea, cutting off Japan from trading and receiving supplies from the rest of the world, thus forcing them to be starved of resources needed for them to fight and sustain their war. Our airforce bombers will also begin nightly bombings for Busan, Tokyo and other major cities, as well as military installations and farms, factories, and other important locations. Any soldier who is captured would be sent to work in our new project, which is a program to build more factories and farms in the new Korean region of the People's Republic of China, which would also help sustain our new population. This is just the first step in a long war, to establish full control over most of east Asia, and bring China to new heights never seen before.
We would also fire large amounts of missiles at important government buildings in Japan and South Korea, in an attempt to wipe out their leadership in one fell swoop.
